The SAR series modules are isolated DC-DC converters with 0% to 100% output voltage programmable by internal reference or external voltage. These modules have an internal reference voltage and shutdown. Protections include input over/undervoltage, over temperature and over programming. Through hole and surface mount packages are available. Every single output has a center tap for a dual output configuration. Due to a resonant design, it exhibits a very low load effect. 0-100% programmable output feature Up to 3W output power 2:1 wide input voltage range with 0.5% line regulation Protected against input over/undervoltage, over temperature and over programming Internal reference voltage feature Shutdown feature Single or dual output configuration Contact Pico for part number of available options: • Expanded operating temp: -55°C to +85°C Stabilization Bake Temperature Cycle Burn-In • Available RoHS Compliant module • Special Input Voltage, Output Voltage, Isolation Voltage or Output Power BLANK = THROUGH HOLE SM = SURFACE MOUNT 2025 REV 2 www.PicoElectronics.com | Series SAR & SAR-SM 443

Series SAR & SAR-SM High Voltage DC-DC TYPICAL CONNECTION CIRCUIT SHUTDOWN ISOLATED Note 1: Shutdown will shut down the unit when the pin is pulled below 0.4V. The unit will restart once the pin reaches operating input voltage. SINGLE OUTPUT OPERATION Note 4: Nominal output voltage is measured between +OUT and -OUT. For single output, COM should be disconnected. DUAL OUTPUT OPERATION Note 5: Nominal output voltage is measured between +OUT and -OUT. For dual outputs, COM will be half of the voltage between +OUT and -OUT. Both loads must be balanced. 2025 REV 2 www.PicoElectronics.com | Series...
