VIPower: LOW COST POWER SUPPLIES
USING VIPer12A IN NON ISOLATED APPLICATIONS


INTRODUCTION
The industrial field is asking for an increasing number of low power low voltage applications both in
isolated and non isolated topology. The main specification is related to the cost of the power converter,
which has to be operated in off-line mode. VIPer12A is a low cost monolithic smart power device with an
integrated PWM controller that is suitable for such applications. In this paper a detailed analysis of
VIPer12A in non isolated applications is performed, exploiting the main features of such a device, in
Buck and Buc
