Description

This demonstration board implements a 15 W

flyback SMPS which is a very popular and much

known topology in applications switch mode

power supplies where the required output power

is in the range of 5 W to 200 W.

The converter is based on the L6565 PWM driver

working in quasi resonant mode, it means zero

voltage switching or at least switching in valley

during turn-off phases and current mode primary

control.

Excellent wide voltage input range from 125 VDC

to 1250 VDC with good efficiency.

STC03DE22HV.

voltage BJT and a low voltage power MOSFET.

STMicroelectronics optimizes performance of

both devices and offers this kind of switch in one

single package to reduce application complexity,

EMI, price and increase reliability and

performance.
