Application note
VIPower: non isolated power supply using
VIPer20 with secondary regulation

Introduction
Output voltage regulation with adjustable feedback compensation loop is very simple when
a VIPer device is used in low cost non-isolated applications. In this paper such a simple
regulation circuit is introduced and analyzed in Buck and Buck-boost converter based on
VIPer20, a monolithic smart power with an integrated PWM controller. The device is suitable
for off-line applicatio
