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

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
as the main switch and a quasi-resonant PWM driver.
This document is associated with the release of the demonstration board
STEVAL-ISA057V1 (Figure 1).
