Product Data Sheet

2 WATT REGULATED

WIDE INPUT RANGE DC/DC CONVERTER

WFC02R

DESCRIPTION

The WFC02R is a family of high performance DC/DC converters

that offers regulated outputs over input voltage ranges of 9-36V

and 18-72V while offering a wide operating temperature range

of -40°C to +85°C without derating.

Each WFC02R 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 WFC02R

converters are designed to withstand input voltage transients to

200% of nominal input voltage. An additional feature is the ability
