Application note

Very wide input voltage range 6 W SMPS for metering

Introduction
This document presents the design of a universal input power supply for metering
applications. The design is mainly based on the following ST parts: an L6565 PWM driver
and STC04IE170HP as the main switch. It is linked with the release of the STEVAL-
IP001Vxx demo board (see Figure 1 below). The design is a complete solution for a 5 W
single output SMPS, which is widely used as a power supply in metering applications.
However the design method can be appl
