Series KR20W Isolated Regulated Low Profile DC-DC ConverterPRODUCT OVERVIEW The KR series is an isolated DC-DC converter with wide input range, tight regulation and six-sided shielded case. These modules have trim and control features. Single and dual isolated output models are standard. They can operate up to 20W over the temperature range of -25°C to +70°C without derating, a heat sink or active cooling. • 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: • Expanded operating temp: -55°C to +85°C 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.

PICO SPECIFICATIONS (Nominal VIN, Full Load, TA = +25°C, 1 hour warm up unless otherwise specified)

Series KR Low Profile DC-DC TYPICAL CONNECTION CIRCUIT SINGLE OUTPUT DUAL OUTPUT SHUTDOWN ISOLATED Please note: During shutdown mode, 475V input and no load condition, the output voltage may increase up to 5% of nominal output voltage. Shutdown is enabled when SHDN pin is pulled low (<1V) relative to -IN. OPEN will automatically restart the module. When floating, the maximum voltage of SHDN is limited to 22VDC.
