The QP series are isolated DC-DC converters with a wide selection of input voltage ranges from 4.5V to 475V while maintaining tight output regulation, low ripple and noise. These modules have trim capability, shutdown and internal reference voltage. Protections include input over/undervoltage, output short-circuit, output overvoltage and over temperature. For increased reliability, the feedback loop does not use an optocoupler. The 2.5” x 1.55” x 0.5” case size has threaded inserts to mount securely for high vibration and shock applications. Conduction cooling is available through the baseplate or compatible heat sink. 4.75V to 475V input range models 5 to 500V output models Up to 50W output Input/output isolation Protected against input over/undervoltage, output short-circuit overcurrent (HiQP) and over temperature Does not use optocoupler in feedback loop External bias for capacitor charging applications (QP) Load Share Parallel operation (HiQP) Industrial temperature option -40°C (HiQP) Military temperature option -55°C (HiQP) Input LC filter for soft start and low reflected current ripple (HiQP) Contact Pico for part number of available options: • Expanded operating temp: -55°C to +85°C (QP) Stabilization Bake Temperature Cycle Burn-In • Special Input Voltage, Output Voltage, Isolation Voltage or Output Power

High Power DC-DC PICO ' MODEL LIST Note 1: Maintain minimum 10% of rated load to prevent a voltage surge. Note 2: Tested at nominal input voltage and full output load. Note 3: Below 5.5V input, derate linearly 7.5W per input voltage. Note 4: Below 10.5V input, derate linearly 6.7W per input voltage.

High Power DC-DC PICO MODEL LIST Note 5: For 6QP, 12QP, 24QP & 48QP models, maintain minimum 10% of rated load to prevent a voltage surge. For HiQP models, maintain minimum 5% of rated load to prevent >2% voltage overshoot.

High Power DC-DC PICO TYPICAL CONNECTION CIRCUIT Note 1: Shutdown will shut down the unit when the pin is pulled below 0.4V. For 6QP, 12QP, 24QP & 48QP models, the voltage of the open shutdown pin is equal to the input voltage. All external components must be rated to at least the input voltage. TRIM UP - HiQP MODELS ONLY TRIM DOWN Note 2: Output Voltage Trim (TRIM) can adjust the output voltage through a resistor to -IN or VREF pins. Note 3: Voltage Reference (VREF) can be used for Output Voltage Trim. Voltage is typically 3V and current is <10mA. Units can be trimmed down with a resistor to...
