B 4/6/07 Page 5 Input: Output: Current: Package: Technical Specification 9-22 V 15.0 V 7A Quarter-brick BASIC OPERATION AND FEATURES CONTROL FEATURES The InQor series converter uses a two-stage power conversion topology. The first stage is a buck-converter that keeps the output voltage constant over variations in line, load, and temperature. The second stage uses a transformer to provide the functions of input/output isolation and voltage step-up or step-down to achieve the output voltage required. REMOTE ON/OFF (Pin 2): The ON/OFF input, Pin 2, permits the user to control when the converter is on or off. This input is referenced to the return terminal of the input bus, Vin(-). The ON/OFF signal is active low (meaning that a low turns the converter on). Figure A details four possible circuits for driving the ON/OFF pin. Figure B is a detailed look of the internal ON/OFF circuitry. Both the first stage and the second stage switch at a fixed frequency for predictable EMI performance. Rectification of the transformer's output is accomplished with synchronous rectifiers. These devices, which are MOSFETs with a very low on-state resistance, dissipate far less energy than Schottky diodes. This is the primary reason that the InQor converter has such high efficiency, even at very low output voltages and very high output currents. Dissipation throughout the converter is so low that it does not require a heatsink for operation in many applications. Since a heatsink is not required, the InQor converter does not need a metal baseplate or potting material to help conduct the dissipated energy to the heatsink. The InQor converter can thus be built more simply and reliably using high yield surface mount techniques on a PCB substrate. Nevertheless, for those thermally demanding applications that require heatsinks or cold-plate mounting, an optional base-plated version of the InQor is available. In addition, for applications having a harsh environment, a totally encased and base-plated version is also available. The InQor series of half-brick and quarter-brick converters uses the industry standard footprint and pin-out configuration. ON/OFF ON/OFF Vin(_) Vin(_) Remote Enable Circuit REMOTE SENSE(+) (Pins 7 and 5): The SENSE(+) inputs correct for voltage drops along the conductors that connect the converter's output pins to the load. Pin 7 should be connected to Vout(+) and Pin 5 should be connected to Vout(-) at the point on the board where regulation is desired. A remote connection at the load can adjust for a voltage drop only as large as that specified in this datasheet, that is [Vout(+) - Vout(-)] - [Vsense(+) - Vsense(-)] < Sense Range % x Vout Pins 7 and 5 must be connected for proper regulation of the output voltage. If these connections are not made, the converter will deliver an output voltage that is slightly higher than its specified value. Note: the output over-voltage protection circuit senses the voltage across the output (pins 8 and 4) to determine when it should trigger, not the voltage across the converter's sense leads (pins 7 and 5). Therefore, the resistive drop on the board should be small enough so that output OVP does not trigger, even during load transients. 5V Negative Logic (Permanently Enabled) ON/OFF 50k 5V ON/OFF 50k TTL TTL/ CMOS ON/OFF Vin(_) Vin(_) Open Collector Enable Circuit Vin(_) Direct Logic Drive Figure A: Various circuits for driving the ON/OFF pin.

B 4/6/07 Page 6 Input: Output: Current: Package: Technical Specification OUTPUT VOLTAGE TRIM (Pin 6): The TRIM input permits the user to adjust the output voltage across the sense leads up or down according to the trim range specifications. To decrease the output voltage, the user should connect a resistor between Pin 6 and Pin 5 (SENSE(-) input). For a desired decrease of the nominal output voltage, the value of the resistor should be Rtrim-down = - 10.22 (511 D%) (kW) where D% = Vnominal - Vdesired Vnominal x 100% To increase the output voltage, the user should connect a resistor between Pin 6 and Pin 7 (SENSE(+) input). For a desired increase of the nominal output voltage, the value of the resistor should be Rtrim-up = ( where 5.11VOUT(100+D%) _ 511 _ 1.225D% D% 10.22 ) (kW) VOUT = Nominal Output Voltage Figure C graphs the relationship between the trim resistor value and Rtrim-up and Rtrim-down, showing the total range the output voltage can be trimmed up or down. Trim Resistance (kOhms) 100,000.0 9-22 V 15.0 V 7A Quarter-brick Total DC Variation of Vout: For the converter to meet its full specifications, the maximum variation of the DC value of Vout, due to both trimming and remote load voltage drops, should not be greater than that specified for the output voltage trim range. PROTECTION FEATURES Input Under-Voltage Lockout: The converter is designed to turn off when the input voltage is too low, helping avoid an input system instability problem, described in more detail in the application note titled "Input System Instability". The lockout circuitry is a comparator with DC hysteresis. When the input voltage is rising, it must exceed the typical Turn-On Voltage Threshold value (listed on the specifications page) before the converter will turn on. Once the converter is on, the input voltage must fall below the typical Turn-Off Voltage Threshold value before the converter will turn off. Output Current Limit: The maximum current limit remains constant as the output voltage drops. However, once the impedance of the short across the output is small enough to make the output voltage drop below the specified Output DC Current-Limit Shutdown Voltage, the converter turns off. The converter then enters a "hiccup mode" where it repeatedly turns on and off at a 5 Hz (nominal) frequency with a 5% duty cycle until the short circuit condition is removed. This prevents excessive heating of the converter or the load board. Output Over-Voltage Limit: If the voltage across the output pins exceeds the Output Over-Voltage Protection threshold, the converter will immediately stop switching. This prevents damage to the load circuit due to 1) excessive series resistance in output current path from converter output pins to sense point, 2) a release of a short-circuit condition, or 3) a release of a current limit condition. Load capacitance determines exactly how high the output voltage will rise in response to these conditions. After 200 ms the converter will automatically restart. 10,000.0 1,000.0 100.0 10.0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 % Increase in Vout % Decrease in Vout Figure C: Trim Graph Note: the TRIM feature does not affect the voltage at which the output over-voltage protection circuit is triggered. Trimming the output voltage too high may cause the over-voltage protection circuit to engage, particularly during transients. Over-Temperature Shutdown: A temperature sensor on the converter senses the average temperature of the module. The thermal shutdown circuit is designed to turn the converter off when the temperature at the sensed location reaches the OverTemperature Shutdown value. It will allow the converter to turn on again when the temperature of the sensed location falls by the amount of the Over-Temperature Shutdown Restart Hysteresis value. It is not necessary for the user to add capacitance at the Trim pin. The node is internally bypassed to eliminate noise.

B 4/6/07 Page 7 Input: Output: Current: Package: Technical Specification APPLICATION CONSIDERATIONS Input System Instability: This condition can occur because any DC/DC converter appears incrementally as a negative resistance load. A detailed application note titled "Input System Instability" is available on the SynQor website which provides an understanding of why this instability arises, and shows the preferred solution for correcting it. Application Circuits: Figure D provides a typical circuit diagram which details the input filtering and voltage trimming. Input Filtering and External Capacitance: Figure E provides a diagram showing the internal input filter components. This filter dramatically reduces input terminal ripple current, which otherwise could exceed the rating of an external electrolytic input capacitor. The recommended external input capacitance is specified in the Input Characteristics section on the Electrical Specifications page. More detailed information is available in the application note titled "EMI Characteristics" on the SynQor website. Startup Inhibit Period: The Startup Inhibit Period ensures that the converter will remain off for approximately 200ms when it is shut down for any reason. When an output short is present, this generates a 5Hz "hiccup mode," which prevents the converter from overheating. In all, there are seven ways that the converter can be shut down, initiating a Startup Inhibit Period: * Input Under-Voltage Lockout * Input Over-Voltage Shutdown (not present in Quarter-brick) * Output Over-Voltage Protection * Over Temperature Shutdown * Current Limit * Short Circuit Protection * Turned off by the ON/OFF input Figure F shows three turn-on scenarios, where a Startup Inhibit Period is initiated at t0, t1, and t2: Before time t0, when the input voltage is below the UVL threshold, the unit is disabled by the Input Under-Voltage Lockout feature. When the input voltage rises above the UVL threshold, the Input Under-Voltage Lockout is released, and a Startup Inhibit Period is initiated. At the end of this delay, the ON/OFF pin is evaluated, and since it is active, the unit turns on.

B 4/6/07 Page 8 Input: Output: Current: Package: Technical Specification At time t1, the unit is disabled by the ON/OFF pin, and it cannot be enabled again until the Startup Inhibit Period has elapsed. When the ON/OFF pin goes high after t2, the Startup Inhibit Period has elapsed, and the output turns on within the typical Turn-On Time. An optional base-plated version is available for applications that require heatsinks, and an encased version is available for harsh environments. Thermal Considerations: Because the InQor series of converters are so efficient, they don't need a heatsink in many applications. Figure 3 shows a power derating curve of an open frame converter for various ambient temperatures and airflow rates. These curves represent a condition which results in a maximum semiconductor junction temperature of 125C, which is comfortable below the 150C ratings of these components. For those applications that are more demanding, or that require a cold-plate mounting, the InQor converters may be purchased with an optional base-plate. The maximum operating base-plate temperature, TB, is 100C. As long as the user's thermal system keeps TB < 100C, the converter can deliver its full rated power. 9-22 V 15.0 V 7A Quarter-brick rate. This information is usually available from the heatsink vendor. The following formula can the be used to determine the maximum power the converter can dissipate for a given thermal condition if its base-plate is to be no higher than 100C. max Pdiss = 100C - TA RTHBA This value of power dissipation can then be used in conjunction with the data shown in Figure 2 to determine the maximum load current (and power) that the converter can deliver in the given thermal condition. For convenience, Figures 5 and 6 provide power derating curves for a converter with a base-plate without a heatsink and with a typical 1/2" high heatsink. RoHS Compliance: The EU led RoHS (Restriction of Hazardous Substances) Directive bans the use of Lead, Cadmium, Hexavalent Chromium, Mercury, Polybrominated Biphenyls (PBB), and Polybrominated Diphenyl Ether (PBDE) in Electrical and Electronic Equipment. This SynQor product is 6/6 RoHS compliant. For more information please refer to SynQor's RoHS addendum available at our RoHS Compliance / Lead Free Initiative web page or e-mail us at rohs@synqor.com. A power derating curve can be calculated for any heatsink that is attached to the base-plate of the converter. It is only necessary to determine the thermal resistance, RTHBA, of the chosen heatsink between the base-plate and the ambient air for a given airflow Vin Under-Voltage Lockout Turn-On Threshold ON/OFF (neg logic) ON OFF ON OFF ON 9ms (typical Vout turn on time) 200ms (typical start-up inhibit period) t1 t0 200ms 200ms t t2 Figure F: Startup Inhibit Period (turn-on time not to scale) Product # IQ12150QTA07 Phone 1-888-567-9596 www.synqor.com Doc.# 005-IQ15007 Rev.
