PRODUCT OVERVIEW The LP series are isolated DC-DC converters with a wide selection of input voltage ranges from 18V to 380V in a compact half brick size foot print - 2.4" x 2.3". These modules have trim capability and shutdown features. Protections include input overvoltage, output short-circuit, output overvoltage and over temperature. The unique case has integrated side heat sink for better thermal dissipation but is capable of conduction cooling through the baseplate or additional top mounted heat sink. FEATURES • 18V to 380V input range models • Input/output isolation • Integrated side heat sink • Parallel operation option • Single and dual isolated outputs • Trim capability • Remote shutdown feature • Fixed operating frequency • No external components required Contact Pico for part number of available options: Stabilization Bake Temperature Cycle Burn-In • Special Input Voltage, Output Voltage, Isolation Voltage or Output Power • Parallel Operation

TYPICAL CONNECTION CIRCUIT TRIM TRIM UP TRIM DOWN TRIM DOWN TRIM DOWN, TRIM Note: Each individual unit will vary slightly. It is recommended to use a 1MO multi-turn trimmer potentiometer to determine resistance value and achieve desired adjustment. Use minimum 1/2W power rating resistor. Keep the trim resistor leads as short as possible to eliminate the stray inductance which will effect the trimming results.
