Series HILR5W Isolated Regulated Low Profile DC-DC Converter PRODUCT OVERVIEW The HILR series is an isolated DC-DC converter with wide and high input voltage range, tight regulation, low ripple and low profile - 0.500" height. These modules are fully protected from input over/undervoltage, output overcurrent, and over temperature. Shutdown feature, single and dual isolated output models are standard. They can operate over the temperature range of -25°C to +70°C without derating, a heat sink or active cooling. FEATURES • Wide input voltage range - 125 to 475V • Down to 0.5% line regulation • Single and dual isolated output • Protected against input over/undervoltage, output overcurrent, and over temperature • 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 HILR 28 S SERIES NAME NOM.

Series HILR 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. www.PicoElectronics.com | Series HILR
