FUNCTIONAL DESCRIPTION

The TEA1501 contains a high voltage power switch, a high

voltage startup circuit and low voltage control circuitry on

the same IC. Together with a transformer and a few

external components a low power, isolated, flyback

converter can be built. The Greeny system operates in a

burst mode. During each burst period the output voltage is

regulated to a desired voltage level.

System operation

ON/OFF

The Greeny system can be switched on and off by means

of a low cost, low voltage switch. In the Off mode the

startup current source and power switch are disabled. In

the On mode, Greeny delivers the startup current for the

supply capacitor and after the supply voltage reaches the

startup level Greeny activates the power switch.

STARTUP

The startup is realized with a high voltage startup current

source instead of a dissipative bleeder resistor which is

commonly used by low voltage control ICs. When Greeny

is switched on, the startup current source is enabled and

starts charging the Vaux capacitor. The startup current

level is high and accurate (typical 1.8 mA) which results in

a well-defined and short startup time, within 0.25 s. After

the supply voltage reaches the startup level the current

source is switched off and the Vaux capacitor supplies the

chip. Reducing the power dissipation in the current source

to zero after startup is one of the green features of Greeny.

OPERATION

After startup the flyback converter starts delivering energy

to the secondary and auxiliary winding. The Greeny

system works with fixed switching frequency and fixed

peak current.

As all the windings of the flyback transformer have the

same flux variation, the secondary voltage and the

auxiliary voltage are related via the turns-ratio (ns/na).

Therefore, the isolated secondary voltage is controlled by

the non-isolated auxiliary voltage.

The burst mode operates by switching at high frequency

until the Vaux voltage reaches its regulation level of 20 V.

Greeny stops switching until the time period set by the

burst oscillator has expired. At the start of the next burst

period Greeny starts switching at high frequency and

repeats the cycle again.

To guarantee a stable operation in a burst mode controlled

system a Vaux slope compensation circuit is integrated in

Greeny. The Greeny system delivers a constant voltage to

the secondary load until a burst duty cycle of 40%.

DATA TRANSFER

The TEA1501 has a data transfer function which makes

communication from the isolated secondary side to the

non-isolated primary side of the transformer possible,

without using an opto-coupler. This communication

function is activated by increasing the secondary load.

With this data transfer function a main power supply can

be switched on and off by the Greeny system.

The power delivered to the secondary and auxiliary

winding is proportional to the number of primary current

pulses per burst period, provided that the converter

operates in discontinuous conduction mode. During each

burst period the number of primary current pulses is

counted. A threshold (Ndata) of 56 pulses is integrated. The

clamp level on the OOD pin is set to data-on level from

data-off level in case the Ndata threshold is passed. This

data-on clamp level can be sensed by the on/off input of a

main supply control IC of the GreenChip family. The

data-on clamp level is maintained until a burst appears

with a number of pulses below the Ndata threshold.

CIRCUIT BLOCK DESCRIPTION

On/Off/Data section

The On/Off/Data block contains a comparator for the on/off

level and is active if the drain voltage is above 50 V (DC).

The typical current consumption in Off mode is 40 µA. The

data signal changes the clamp level on the OOD pin to

indicate data transfer: low clamp level for data-off and high

clamp level for data-on.

Vaux management

The Vaux management block is active when Greeny is in

the On mode. This Vaux management block senses the

Vaux voltage and determines the state of Greeny: startup

or normal operation. During startup the following circuits

are active: On/Off/Data section, Reference block (partial),

Vaux management, Temperature protection and the

Startup current source.

Startup current source

The startup sequence is carried out using an accurate

startup current source. The startup current flows from the

Drn pin to the Vaux pin via the startup current source and

charges the Vaux capacitor. When Vaux reaches the

startup threshold the startup current is switched off and the

flyback converter starts operating and the output voltage

rises. The Vaux capacitor must be capable of supplying

the entire supply current (IVaux(LOW)) until the output

voltage is in regulation. From that moment the Vaux

capacitor is charged by the flyback converter via the

auxiliary winding.

Reference block

The reference block contains a bandgap circuit which

determines all the accurate and temperature independent

reference voltages and currents. It defines the voltage

detection level for the primary current comparator and it

defines the voltage at the Ref pin. The value of the

reference resistor determines the burst frequency, the

switching frequency and the leading edge blanking time.

Temperature protection

The temperature protection circuit senses the chip

temperature using a proportional to absolute temperature

voltage (Vptat) generated in the reference block. If the chip

temperature exceeds 140 °C the power switch and the

startup current source are disabled. When the chip cools

down below 100 °C, the startup circuit is enabled again.

Switch oscillator

The switch oscillator determines the switching frequency

and the maximum on-time of the power switch. The

maximum on-time is set at 66% of the switching period.

The switching frequency is determined by the reference

resistor at the Ref pin and an internal capacitor. The

switching frequency can be adjusted in a range from

20 to 50 kHz, thus above the audible spectrum.

1998 Aug 19 8

Philips Semiconductors Preliminary speciﬁcation

Greeny; GreenChipTEA1501

Burst oscillator

The burst oscillator generates a triangular wave signal for

determination of the burst frequency. The burst frequency

is determined accurately and temperature independent by

the externally connected reference resistor RRef and burst

capacitor CBt.

Gate driver

The gate driver switches the power switch. The power

switch is turned on at the beginning of every oscillator

cycle and is turned off by the primary current comparator

or by the maximum on-time. The power switch is also

prevented from turning on if the Vaux voltage has reached

its regulation level or in case of active over temperature

protection or in case of active under voltage lockout

protection.

Power switch

The power switch is an integrated high voltage LDMOST

with a Rdson of 40 Ω, a maximum peak drain voltage of

650 V,a maximum continuous drain voltage of 500 V and

a maximum drain current of 0.25 A.

Primary current comparator

The primary current comparator senses the voltage across

the external sense resistor RSrc which reflects the primary

current. The detection level of the comparator is 0.5 V. The

power switch is switched off quickly when the source

voltage exceeds this detection level. The comparator has

a typical propagation delay of 80 ns. If the dV/dt of the

drain voltage has to be limited for EMI reasons, a capacitor

can be connected between the Drn and Src pins of

Greeny. The discharge current of this EMI capacitor does

not flow through the sense resistor RSrc and does not

activate the comparator.

Leading edge blanking

To prevent the power switch from switching off due to the

discharge current of the capacitance on the Drn pin a

Leading Edge Blanking (LEB) circuit has been

implemented. The leading edge blanking time is defined

as the maximum duration time needed to discharge the

capacitance at the drain of the power switch. The leading

edge blanking time is determined by the reference resistor

to obtain an accurate and temperature independent time.

The LEB time tracks with the period time of the switch

oscillator.

Modulator

The modulator determines the regulation level of the Vaux

voltage. For a burst duty cycle from 0 to 40% the Vaux

voltage is regulated to 20 V. For stable operation in burst

mode a decrease in regulation voltage is integrated for a

burst duty cycle above 40%. At 100% burst duty cycle the

regulation voltage is 17.5 V.

Counter

The power delivered to the load (auxiliary and secondary)

is a function of the number of energy pulses per burst,

according to the following formula:

Whereη is the efficiency, Lp is the primary inductance, Iprim

is the primary peak current, fburst is the burst frequency and

N is the number of pulses in one burst period.

The counter counts the number of pulses in each burst

period and detects if the Ndata threshold is passed. The

counter state is used for the data transfer function and for

the supply current tracking.

Supply current tracking

For obtaining good load regulation, especially with low

cost transformers, a tracking circuit is included. The

tracking circuit makes the supply current of Greeny a

function of the secondary load. This makes the voltage

drop across the series resistance of the auxiliary winding

proportional to the voltage drop across the series

resistance of the secondary winding. Therefore, the

secondary output voltage tracks with the Vaux regulation

voltage.

The tracking starts at a counter state of 28. For a counter

state from 28 up to 112 (typical values) the supply current

of Greeny rises linearly with the counter state according to

the following formula (see Fig.7).

For counter states of 112 and higher the supply current

remains on its maximum value.

DESIGN EQUATIONS

Primary peak current

The primary peak current is determined by the sense

resistor RSrc and may be calculated as shown below:

MINIMUM VALUE OF RSrc

The maximum drain current is 0.25 A, this results in a

minimum value for resistor RSrc of 2.0 Ω.

Switch oscillator

The maximum output power of the converter is a function

of the switching frequency, provided that the converter

operates in discontinuous conduction mode.

Where η is the efficiency, Lp is the primary inductance,

Iprim is the primary peak current and fswitch is the switching

frequency.

The switching frequency can be adjusted between

20 and 50 kHz by the reference resistor RRef:

RANGE OF RRef VALUES

The minimum value for resistor RRef is 24 kΩ, the

maximum value is 62 kΩ.

Leading edge blanking

The leading edge blanking time is determined by the

reference resistor RRef as shown below:

The leading edge blanking time consists of a constant time

and a time which tracks with the period time of the switch

LOW POWER STANDBY APPLICATION

Greeny can operate as a stand alone low power supply or

as a standby power supply incorporated in a main SMPS.

Together with a GreenChip TEA1504 a power supply

with ultra low standby power can be built where Greeny

supplies the microprocessor with the power on/off

indicator and the GreenChip controls the main power

supply during normal operation.

Operation modes

The power supply with a Greeny TEA1501 and a

GreenChip TEA1504 can be in three different modes,

according to the state of switches S1 and S2 (see Fig.9).

Table 1 Operation modes of power supply

Power supply in Off mode

The power supply can be switched on and off by means of

the functional switch S1. This functional switch replaces

the generally used high voltage mains switch. The power

supply is in Off mode if the switch S1 is open.

If the switch S1 is closed the voltage applied on the OOD

pin of Greeny is above the on/off level (0.7 V) and Greeny

starts up, the power supply enters the Standby mode or

the Normal operation mode.

S1 S2 OPERATION MODE

Open Open or

Closed Greeny is in Off mode,

GreenChip is in Off mode, Power

supply is in Off mode.

Closed Open Greeny is On mode,

GreenChip is in Off mode,

Power supply is in Standby mode.

Closed Closed Greeny is in On mode,

GreenChip is in On mode,

Power supply is in Normal

operation mode.

When the switch S1 is opened the voltages on the OOD

pin of Greeny and the OOB pin of the GreenChip are 0 V.

The power supply and the power on/off indicator (LED) are

switched off immediately and the power supply is in the

Off mode again.

Power supply in Standby mode

When switch S1 is closed Greeny is in the On mode and

supplies the microprocessor and the power on/off

indicator. The microprocessor controls the state of switch

S2. The power supply is in the Standby mode when switch

S2 is open.

The output power of Greeny is determined by the

microprocessor and is below the Pdata level when switch

S2 is open. The clamp level on the OOD pin of Greeny is

the data-off level with a typical value of 1.3 V which is

below the on/off level of the GreenChip which has a

typical value of 2.5 V. The GreenChip remains in Off

mode.

Power supply in Normal operation mode

The power supply changes its operation mode from

Standby to Normal operation by closing the switch S2. The

switch S2 is placed at the isolated secondary side of the

Greeny and controls, via the data transfer function of

Greeny, the operation mode of the power supply.

When the microprocessor closes switch S2 the output

power of Greeny is increased. The output power exceeds

the Pdata level and the clamp level on the OOD pin of

Greeny is set to data-on level with a value of 4 V. The

voltage on the OOB pin of the GreenChip is above its

on/off level of 2.5 V and the GreenChip starts up.

The power supply enters Normal operation mode, Greeny

supplies the microprocessor and the GreenChip supplies

the main load.

SOLDERING

Introduction

There is no soldering method that is ideal for all IC

packages. Wave soldering is often preferred when

through-hole and surface mounted components are mixed

on one printed-circuit board. However, wave soldering is

not always suitable for surface mounted ICs, or for

printed-circuits with high population densities. In these

situations reflow soldering is often used.

This text gives a very brief insight to a complex technology.

A more in-depth account of soldering ICs can be found in

our

“Data Handbook IC26; Integrated Circuit Packages”

(order code 9398 652 90011).

Soldering by dipping or by wave

The maximum permissible temperature of the solder is

260 °C; solder at this temperature must not be in contact

with the joint for more than 5 seconds. The total contact

time of successive solder waves must not exceed

5 seconds.

The device may be mounted up to the seating plane, but

the temperature of the plastic body must not exceed the

specified maximum storage temperature (Tstg max). If the

printed-circuit board has been pre-heated, forced cooling

may be necessary immediately after soldering to keep the

temperature within the permissible limit.

Repairing soldered joints

Apply a low voltage soldering iron (less than 24 V) to the

lead(s) of the package, below the seating plane or not

more than 2 mm above it. If the temperature of the

soldering iron bit is less than 300 °C it may remain in

contact for up to 10 seconds. If the bit temperature is

between 300 and 400 °C, contact may be up to 5 seconds.
