Summary
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.
