| Product Data Sheet 2:1 WIDE INPUT RANGE DC/DC CONVERTER WPC10R DESCRIPTION The WPC10R is a family of high performance DC/DC converters that offer regulated outputs over two input voltage ranges of 18 - 36 and 28 - 75V and over a wide operating temperature range of -40C to +100C without derating. The 350kHz switching frequency and forward converter topology provide optimum performance in a spacesaving package. The design uses all surface mounted components, including magnetics, to provide enhanced reliability. All models will operate even under no-load conditions, although a minimum load is specified for load regulation measurement purposes. A metal package is utilized for decreased radiated noise and an optional remote enable feature allows low power standby operation.
