Description

The SW/SC series power modules are isolated dc-dc converters that operate over a wide range of input voltage (VIN

= 18 - 36Vdc for SC modules and VIN = 36 – 75Vdc for SW modules) and provide a single precisely regulated

output. This series is a low cost, smaller size alternative to the existing LW/LAW/LC with enhanced performance

parameters. The output is fully isolated from the input, allowing versatile polarity configurations and grounding

connections. The modules exhibit high efficiency, typical efficiency of 86% for 5.0V/3A. Built-in filtering for both

input and output minimizes the need for external filtering.

RoHS Compliant

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are

absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in

excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for

extended periods can adversely affect the device reliability.

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power module can be used in a wide variety of applications, ranging from simple standalone operation to being

part of complex power architecture. To preserve maximum flexibility, internal fusing is not included; however, to

achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-

acting fuse with a maximum rating of 3A (see Safety Considerations section). Based on the information provided in

this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be

used. Refer to the fuse manufacturer’s data sheet for further information.

Design Considerations

Input Source Impedance

The power module should be connected to a low

ac-impedance source. Highly inductive source

impedance can affect the stability of the power module.

For the test configuration in Figure 43, a 33μF

electrolytic capacitor (ESR<0.7Ω at 100kHz), mounted

close to the power module helps ensure the stability of

the unit. Consult the factory for further application

guidelines.

Safety Considerations

For safety-agency approval of the system in which the

power module is used, the power module must be

installed in compliance with the spacing and separation

requirements of the end-use safety agency standard,

i.e., UL 60950-1-3, CSA C22.2 No. 60950-00, and VDE

0805 (IEC60950, 3rd Edition).

If the input source is non-SELV (ELV or a hazardous

voltage greater than 60 Vdc and less than or equal to

75Vdc), for the module’s output to be considered as

meeting the requirements for safety extra-low voltage

(SELV), all of the following must be true:

 The input source is to be provided with reinforced

insulation from any other hazardous voltages,

including the ac mains.

 One VIN pin and one VOUT pin are to be grounded,

or both the input and output pins are to be kept

floating.

 The input pins of the module are not operator

accessible.

 Another SELV reliability test is conducted on the

whole system (combination of supply source and

subject module), as required by the safety agencies,

to verify that under a single fault, hazardous

voltages do not appear at the module’s output.

Note: Do not ground either of the input pins of the

module without grounding one of the output pins.

This may allow a non-SELV voltage to appear

between the output pins and ground.

The power module has extra-low voltage (ELV) outputs

when all inputs are ELV.

For input voltages exceeding –60 Vdc but less than or

equal to –75 Vdc, these converters have been evaluated

to the applicable requirements of BASIC INSULATION

between secondary DC MAINS DISTRIBUTION input

(classified as TNV-2 in Europe) and unearthed SELV

outputs.

The input to these units is to be provided with a

maximum 3A time-delay fuse in the ungrounded lead.

Feature Description

Remote On/Off

Two remote on/off options are available. Positive logic

turns the module on during a logic high voltage on the

ON/OFF pin, and off during a logic low. Negative logic

remote On/Off, device code suffix “1”, turns the module

off during a logic high and on during a logic low.

To maintain compatibility with LW series power modules

the Remote On/Off pin is optional for the TH (through

hole) version. Standard TH modules have no On/Off pin

fitted. TH modules ordered with device code suffix “1”

are negative logic with the On/Off pin fitted. The On/Off

pin shall always be fitted on SMT versions.

Figure 46. Circuit configuration for using Remote

On/Off Implementation.

To turn the power module on and off, the user must

supply a switch (open collector or equivalent) to control

the voltage (Von/off) between the ON/OFF terminal and

the VIN(-) terminal. Logic low is 0V ≤ Von/off ≤ 1.2V. The

maximum Ion/off during a logic low is 1mA, the switch

should be maintain a logic low level whilst sinking this

current.

During a logic high, the typical Von/off generated by the

module is 5.8V, and the maximum allowable leakage

current at Von/off = 5.8V is 50μA.

If not using the remote on/off feature:

For positive logic, leave the ON/OFF pin open.

For negative logic, short the ON/OFF pin to VIN(-).

Overcurrent Protection

To provide protection in a fault (output overload)

condition, the unit is equipped with internal

current-limiting circuitry and can endure current limiting

continuously. At the point of current-limit inception, the

unit enters hiccup mode. The unit operates normally

once the output current is brought back into its specified

range. The average output current during hiccup is 10%

IO, max.

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout

limit, the module operation is disabled. The module will

only begin to operate once the input voltage is raised

above the undervoltage lockout turn-on threshold,

VUV/ON.

Once operating, the module will continue to operate until

the input voltage is taken below the undervoltage turn-off

threshold, VUV/OFF.

Over Voltage Protection

The output overvoltage protection consists of circuitry

that internally clamps the output voltage. If a more

accurate output overvoltage protection scheme is

required then this should be implemented externally via

use of the remote on/off pin.

Output Voltage Programming

Trimming allows the user to increase or decrease the

output voltage set point of the module. This is

accomplished by connecting an external resistor

between the TRIM pin and either the Vout+ pin or the

Vout- pin.

Note: Trim pin is optional on TH module version and

always present on SMT versions.

Trim Down – Decrease Output Voltage

By connecting an external resistor between the TRIM pin

and Vout+ pin (Radj-down), the output voltage set point

decreases (see figure 17). The following equation

The combination of the output voltage adjustment and

the output voltage initial tolerance must not exceed the

allowable trim range of 90% to 110% of the nominal

output voltage as measured between the Vout+ and

Vout- pins.

The SW/SC power modules have a fixed current-limit set

Thermal Considerations

The power modules operate in a variety of thermal

environments; however, sufficient cooling should be

provided to help ensure reliable operation.

Considerations include ambient temperature, airflow,

module power dissipation, and the need for increased

reliability. A reduction in the operating temperature of the

module will result in an increase in reliability. The

thermal data presented here is based on physical

measurements taken in a wind tunnel.

The thermal reference point, Tref used in the

specifications is shown in Figure 49. For reliable

operation this temperature should not exceed 120oC.

Tref

Figure 49. Tref Temperature Measurement Location.

Heat Transfer via Convection

Increased airflow over the module enhances the heat

transfer via convection. Derating figures showing the

maximum output current that can be delivered by each

module versus local ambient temperature (TA) for natural

convection and up to 3m/s (600 ft./min) are shown in the

respective Characteristics Curves section.

Please refer to the Application Note “Thermal

Characterization Process For Open-Frame Board-

Mounted Power Modules” for a detailed discussion of

thermal aspects including maximum device

temperatures.

Layout Considerations

The SW/SC power module series are low profile in order

to be used in fine pitch system card architectures. As

such, component clearance between the bottom of the

power module and the mounting board is limited. Avoid

placing copper areas on the outer layer directly

underneath the power module. Also avoid placing via

interconnects underneath the power module.

For additional layout guide-lines, refer to the

FLTR100V10 data sheet.

LINEAGE POWER 21

The SW/SC family of power modules is available for

either Through-Hole (TH) or Surface Mount (SMT)

soldering.

Through-Hole Soldering Information

The RoHS-compliant (Z codes) through-hole products

use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-

compliant components. They are designed to be

processed through single or dual wave soldering

machines. The pins have an RoHS-compliant finish

that is compatible with both Pb and Pb-free wave

soldering processes. A maximum preheat rate of

3°C/s is suggested. The wave preheat process

should be such that the temperature of the power

module board is kept below 210°C. For Pb solder,

the recommended pot temperature is 260°C, while the

Pb-free solder pot is 270°C max. Not all RoHS-

compliant through-hole products can be processed

with paste-through-hole Pb or Pb-free reflow process.

If additional information is needed, please consult with

your Lineage Power representative for more details.

Surface Mount Information

Pick and Place

The SW/SC-SR series of DC-to-DC power converters

use an open-frame construction and are designed for

surface mount assembly within a fully automated

manufacturing process.

The SW/SC-SR series modules are designed to use

the main magnetic component surface to allow for

pick and place.

Z Plan e Height

The ‘Z’ plane height of the pick and place location is

7.50mm nominal with an RSS tolerance of +/-0.25

mm.

Nozzle Recommendations

The module weight has been kept to a minimum by

using open frame construction. Even so, they have a

relatively large mass when compared with

conventional SMT components. Variables such as

nozzle size, tip style, vacuum pressure and placement

speed should be considered to optimize this process.

The minimum recommended nozzle diameter for

reliable operation is 5mm. The maximum nozzle outer

diameter, which will safely fit within the allowable

component spacing, is 6.5mm.

Oblong or oval nozzles up to 11 x 6 mm may also be

used within the space available.

For further information please contact your local

Lineage Power Technical Sales Representative.

Reflow Soldering Information

These power modules are large mass, low thermal

resistance devices and typically heat up slower

than other SMT components. It is recommended

that the customer review data sheets in order to

customize the solder reflow profile for each

application board assembly.

The following instructions must be observed when

SMT soldering these units. Failure to observe

these instructions may result in the failure of or

cause damage to the modules, and can adversely

affect long-term reliability.

The surface mountable modules in the SW/SC

family use our SMT technology called “Column Pin”

(CP) connectors. Figure 53 shows the CP

connector before and after reflow soldering onto the

end-board assembly.

Power Module Board

Insulator

Solder Ball

End assembly PCB

Figure 53. Column Pin Connector Before and

After R e fl ow Solderin g .

The CP is constructed from a solid copper pin with an

integral solder ball attached, which is composed of

tin/lead (Sn63/Pb37) solder for non-Z codes, or

Sn/Ag3.8/Cu0.7 (SAC) solder for –Z codes. The CP

connector design is able to compensate for large

amounts of co-planarity and still ensure a reliable

SMT solder joint. Typically, the eutectic solder melts

at 183oC (Sn/Pb solder) or 217-218 oC (SAC solder),

wets the land, and subsequently wicks the device

connection. Sufficient time must be allowed to fuse

the plating on the connection to ensure a reliable

solder joint.

Surface Mount Information (continued)

There are several types of SMT reflow technologies

currently used in the industry. These surface

mount power modules can be reliably soldered

using natural forced convection, IR (radiant

infrared), or a combination of convection/IR. The

recommended linear reflow profile using Sn/Pb

solder is shown in Figure 54 and 55. For reliable

soldering the solder reflow profile should be

established by accurately measuring the modules

Lead Free Soldering

The –Z version SMT modules of the SW/SC series

are lead-free (Pb-free) and RoHS compliant and are

compatible in a Pb-free soldering process. Failure to

observe the instructions below may result in the

failure of or cause damage to the modules and can

adversely affect long-term reliability.

Pb-free Reflow Profile

Power Systems will comply with J-STD-020 Rev. C

(Moisture/Reflow Sensitivity Classification for

Nonhermetic Solid State Surface Mount Devices) for

both Pb-free solder profiles and MSL classification

procedures. This standard provides a recommended

forced-air-convection reflow profile based on the

volume and thickness of the package (table 4-2). The

suggested Pb-free solder paste is Sn/Ag/Cu (SAC).

MSL Rating

Storage and Handling

The recommended storage environment and handling

procedures for moisture-sensitive surface mount

packages is detailed in J-STD-033 Rev. A (Handling,

Packing, Shipping and Use of Moisture/Reflow

Sensitive Surface Mount Devices). Moisture barrier

bags (MBB) with desiccant are required for MSL

ratings of 2 or greater. These sealed packages

should not be broken until time of use. Once the

original package is broken, the floor life of the product

at conditions of ≤ 30°C and 60% relative humidity

varies according to the MSL rating (see J-STD-033A).

The shelf life for dry packed SMT packages will be a

minimum of 12 months from the bag seal date, when

stored at the following conditions: < 40° C, < 90%

relative humidity.

Post Solder Cleaning and Drying

Considerations

Post solder cleaning is usually the final circuit-board

assembly process prior to electrical board testing. The

result of inadequate cleaning and drying can affect

both the reliability of a power module and the

testability of the finished circuit-board assembly. For

quantity and lead times. Legacy device codes may contain a –B option suffix to indicate 100% factory Hi-Pot tested to

the isolation voltage specified in the Absolute Maximum Ratings table. The 100% Hi-Pot test is now applied to all

device codes, with or without the –B option suffix. Existing comcodes for devices with the –B suffix are still valid;

however, no new comcodes for devices containing the –B suffix will be created.

** When adding multiple options to the product code, add numerical suffix codes in the descending order.

† Either negative or positive logic (1 or 4), and output voltage adjustment (trim, 9) must be ordered on surface mount ,

SMT (-SR) device codes. Both the on/off pin and trim pin will be provided on all –SR device codes.
