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 V
DC
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.
