| 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 -40C to +85C without derating. Each WPC03R contains input filtering to minimize conducted noise. The design utilizes surface mounted components, including magnetics, to provide enhanced reliability. 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. FEATURES Low Cost, High Performance Small DIP Package Full Power to +85C Extended Temperature Range: -40C to +85C Industry Standard Pinouts Full Short Circuit Protection High Capacitive Loading Capability Protected Against High Input Voltage APPLICATIONS Telecommunications Battery Powered Systems Portable Instruments Transportation Equipment Distributed Power Systems SIMPLIFIED CIRCUIT SCHEMATIC Internet: http://www.cdpoweronline.com WPC03R 2/99 REV A Page 1 ABSOLUTE MAXIMUM RATINGS Output Short Circuit Protection ----------------- Continuous Internal Power Dissipation --------------------------------- 1.5W Lead Temp (soldering, 10s Max) ----------------------- +300C Max Case Temperature ----------------------------------- +100C ELECTRICAL SPECIFICATIONS Specifications typical at TA=25C, nominal input voltage, rated output current unless otherwise stated.
