The VIPer12A is an integrated PWM and MOSFET circuit for low power application in the 5W range, typically in Cellular Phone Adapters. It is housed in surface mount SO-8 and DIP8 packages.
With the availability of VIPer12A in SO-8 package and the limited number of external components for a real PWM operation, building a compact and performant power supply becomes simple.
The travel adaptor design presented here, has been made with the aim of minimising overall cost for a secondary voltage and current regulated adapter, topology widely used in Cellular Phone Adapters.
