Series MR2.5W Isolated Regulated Low Profile DC-DC ConverterPRODUCT OVERVIEW The MR series are regulated DC-DC converters with upgraded MIL screened / qualified components and expanded operating temperature range. The 6-sided epoxy insulated shielded case is in a low profile package - 1.900” x 1.000” x 0.300". Over 40 models are available in both single and dual isolated outputs. They can operate over the wide temperature range of -55°C to +85°C without derating, a heat sink or active cooling. • JANTX Diodes • MIL screened transformers, capacitors and resistors • Hermetically sealed transistors • Up to 3.33:1 input voltage range • Six-sided shielded case • Control feature • Trimmable output • Input/output isolation • Single and dual isolated output • No external components required • No heat sink or derating 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

PICO MODEL LIST SINGLE OUTPUT Note 1: Tested at nominal input voltage and full output load. Note 2: Line regulation is specified at full output load, nominal to minimum input voltage (-%) and nominal to maximum input voltage (+%). Note 3: Load regulation is specified at nominal input voltage, 60% to 25% load (+%) and 60% to 100% load (-%).

PICO MODEL LISTDUAL OUTPUT Pico Note 1: Tested at nominal input voltage and full output load. Note 2: Line regulation is specified at full output load, nominal to minimum input voltage (-%) and nominal to maximum input voltage (+%). Note 3: Load regulation is specified at nominal input voltage, 60% to 25% load (+%) and 60% to 100% load (-%). Note 4: Dual outputs must be balanced.
