B 03/18/15 Page 8 MQSA-28-05S Output: 5.0 V Current: 1.0 A Application Section BASIC OPERATION AND FEATURES The MQSA DC/DC converter uses a single stage power conversion topology. A flyback-converter is used to keep the output voltage constant over variations in line, load, and temperature. The converter switches at a fixed frequency for predictable EMI performance. Rectification of the output is accomplished with diodes. An input under-voltage shutdown feature with hysteresis is provided, as well as an output over-voltage limit. There is also an output current limit that is nearly constant as the load impedance decreases. When a load fault is removed, the output voltage rises exponentially to its nominal value with minimal overshoot. The following sections describe the use and operation of additional control features provided by the MQSA converter. CONTROL FEATURES ENABLE: The MQSA converter has one enable pin, ENA (pin 5), which is referenced with respect to the converter’s input return (pin 7). It must have a logic high level for the converter to be enabled; a logic low inhibits the converter. The enable pin is internally pulled high so that an open connection will enable the converter. Figure A shows the equivalent circuit looking into the enable pin. It is TTL compatible and has hysteresis. SHUT DOWN: The MQSA converter will shut down in response to only three conditions: ENA input low, VIN input below under-voltage shutdown threshold, and output voltage above the output over-voltage threshold. INPUT UNDER-VOLTAGE SHUTDOWN: The MQSA converter has an under-voltage shutdown feature that ensures the converter will be off if the input voltage is too low. The input voltage turn-on threshold is higher than the turn-off threshold. +VIN 200 K PIN 5 (ENABLE) TO ENABLE CIRCUITRY 4.99K 18 .7K OUTPUT OVER-VOLTAGE SHUTDOWN: The MQSA converter will shut down if the voltage at its power output pins ever exceeds about 130% of the nominal value. CURRENT LIMIT: In the event of excess load, the MQSA converter will quickly reduce its output voltage to keep the load current within safe limits. If the converter is connected to an external heatsink, the heatsink will help to make the converter’s case top a uniform temperature. How well it does so depends on the thickness of the heatsink and on the thermal conductance of the interface layer (e.g. thermal grease, thermal pad, etc.) between the case and the heatsink. Unless this is done very well, it is important not to mistake the heatsink’s temperature for the maximum case temperature. It is easy for them to be as much as 5-10ºC different at full power and at high temperatures. It is suggested that a thermocouple be attached directly to the converter’s case through a small hole in the heatsink when investigating how hot the converter is getting. Care must also be made to ensure that there is not a large thermal resistance between the thermocouple and the case due to whatever adhesive might be used to hold the thermocouple in place. 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. THERMAL CONSIDERATIONS: Figure 5 shows the suggested Power Derating Curves for this converter as a function of the case temperature and the maximum desired power MOSFET junction temperature. All other components within the converter are cooler than its hottest MOSFET, which at full power is no more than 20ºC higher than the case temperature directly below this MOSFET. The Mil-HDBK-1547A component derating guideline calls for a maximum component temperature of 105ºC. Figure 5 therefore has one power derating curve that ensures this limit is maintained. It has been SynQor’s extensive experience that reliable long-term converter operation can be achieved with a maximum component temperature of 125ºC. In extreme cases, a maximum temperature of 145ºC is permissible, but not recommended for long-term operation where high reliability is required. Derating curves for these higher temperature limits are also included in Figure 5. The maximum case temperature at which the converter should be operated is 135ºC.
