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
