The QP unit will not start-up under a short-cuicuit condition because the Internal Bias Supply cannot develop the required start-up voltage. To charge up a large capacitor, an external bias voltage should be used only until the output voltage, Vout, reached 90 - 95% of its nominal value and therefore the internal bias voltage has come up and is able to sustain converter operation. Note that during External Bias operation, output overload and short circuit protection are disabled and for this reason it is highly recommended - as shown in diagram - to disable the External Bias supply after Vout reaches its nominal value and allow from that moment on for the internal bias voltage operation. While on internal bias operation, overload and short circuit protections are restored. For additional information, see Application Notes.

PIN DESCRIPTION Pin # 1 (-IN): Negative Input Voltage to the unit, 9-18V (12QP Series) or 1836V (24 QP Series). Units are Input UV/OV protected, nonlatched shutdown. Pin # 2 (SHDN): When pulled below 0.4Vdc will cause the unit to shut down, non-latching. Pin # 3 (VREF): 3Vref generated on board. Range 2.8Vdc to 3.2Vdc Current sourcing capability: 10mA max. http://www.picoelectronics.com/dcdclow/peQP.htm?PartNo=12QP300* 12/18/2007 Pico Electronics: QP SERIES Page 9 of 13 Pin # 4 (TRIM): Connecting this pin through a resistor to -IN will increase V OUT. Connecting it through a resistor to VREF will reduce V OUT. Adjusting range is max. +/- 5% V OUT. PIN #1 #2 #3 #4 #5 #6 #7 #8 FUNCTION -IN SHDN VREF TRIM EX. B +IN +OUT -OUT Pin # 5 (EX.B): This pin is a direct path to the controller IC's Vcc and should not exceed 20Vdc otherwise the IC will be damanged. External Bias (Ex.B) will enable applications where the unit has to start up under an overload or shortcircuit condition (like capacitor charging applications). Overload conditions will prevent internal bias supply to develop the start-up voltage due to the hiccup protection mode and unit will not start. Required voltage for Ex.B start up: 17 to 20Vdc. Caution: when operated with Ex.B, the unit loses overload and shor circuit protection. Do not connect if Pin # 5 is not used. Pin # 6 (+IN): Positive Input Voltage to the unit. Pin # 7 (+OUT): Positive Output Voltage. A minimum 10% load across the output is required in order to provide regulation. Output is clamped with Zener diodes at a 120% V OUT (typical) to limit overshoot in case of no load operation.
