Application note
15 W wide range SMPS for metering
based on ESBT STC03DE220HV and L6565 PWM controller

1 Introduction

This document describes a 15-W flyback switched mode power supply (SMPS) application
that uses an emitter-switched bipolar transistor (ESBT) switch (STC03DE220HV) and
L6565 quasi-resonant pulse-width modulation (PWM) controller.
The application is a universal, cost-effective flyback converter used in metering applications,
with an excellent wide-voltage input range from 125 to 1250 VDC, achieved using the ESBT
