300W Isolated Regulated High Power DC-DC ConverterPRODUCT OVERVIEW The XP series are isolated DC-DC converters with 2:1 input voltage ranges and high 300W output power in a low profile full brick size - 4.6" x 2.4" x 0.5". These modules have trim capability, shutdown features and frequency sync. Protections include input overvoltage, output short-circuit, output overvoltage and over temperature. The case has six threaded inserts to mount securely for high vibration and shock applications. Conduction cooling is available through the baseplate or compatible heat sink. FEATURES • 2:1 input range models • Input/output isolation • Single outputs • Up to +85°C baseplate operating temperature • Trim capability • Remote shutdown feature • Operating Frequency sync feature • Fixed operating frequency • No external components required Contact Pico for part number of available options: • Expanded operating temp: -55°C to +85°C Stabilization Bake Temperature Cycle Burn-In • Special Input Voltage, Output Voltage, Isolation Voltage or Output Power XP A -28S SERIES NAME INPUT VOLTAGE RANGE NOMINAL OUTPUT VOLTAGE

Note 1: Tested at nominal input voltage and full output load. Note 2: Maintain minimum 10% of rated load to prevent a voltage surge. Note 3: Deate 10% power per input voltage for 18-21V

Series XP High Power DC-DC TYPICAL CONNECTION CIRCUIT SHUTDOWN REMOTE SENSE LOCAL SENSE VOUT = VLOAD + VWIRE 1 + VWIRE 2 VLOAD = VOUT - VWIRE 1 - VWIRE 2 The positive remote sense (+SENSE) should be connected to the positive output (+VOUT) at the physical load location. The negative remote sense (-SENSE) should be connected to the negative output (-VOUT) at the physical load location. VOUT may compensate up to 1V of drop in the load wires. Voltage will be regulated at the load. Alternatively, for local sense, +SENSE should be connected to +VOUT and -SENSE should be connected to -VOUT at the output...
