Features

Angel operation

Description

This evaluation board is an offline, wide-range,

VIPer22A-E dual-output power supply with a

switching frequency of 60 kHz and is set up for

secondary regulation with an optocoupler. One

output delivers 5 V at 1 A and a second output

delivers 12 V at 0.42 A, making for a total output

power of 10 W. The evaluation board meets Blue

Angel Norms, consuming less than 1 W total

when working in standby mode. The board

operates in burst mode when both the output

loads are reduced to zero and the output voltages

still remain regulated.
