Product Data Sheet 3 WATT REGULATED WIDE INPUT RANGE DC/DC CONVERTER WPC03R DESCRIPTION The WPC03R is a family of high performance DC/DC converters that offers regulated outputs over input voltage ranges of 9-18V, 18-36V and 34-72V while offering a wide operating temperature range of -40°C to +85°C without derating. Each WPC03R contains input filtering to minimize conducted noise. The design utilizes surface mounted components, including magnetics, to provide enhanced reliability. FEATURES l l l l l l l l Low Cost, High Performance Small DIP Package Full Power to +85°C Extended Temperature Range: -40°C to +85°C Industry Standard Pinouts Full Short Circuit Protection High Capacitive Loading Capability Protected Against High Input Voltage APPLICATIONS l l l l l The converter is designed to meet the requirements of EN60950 with the “L” pinout having 1,500 VDC isolation. All WPC03R converters are designed to withstand input voltage transients to 200% of nominal input voltage. An additional feature is the ability of the WPC03R to drive high capacitive loads.
