Reference design genaral

description

The travel adaptor design presented here has

been made with the aim of minimizing overall cost

for a secondary voltage and current regulated

adapter topology widely used in cellular phone

adapters. Thanks to the VIPer12A low power

consumption, it is possible to achieve 100mW

standby power in a wide range of operations, as

recommended by the "European Commission of

Energy".
