Description

This demonstration board is a 125 W adapter

using ESBT switch STP12IE95F4, the L6565

quasi-resonant PWM controller and the STSR30

smart driver IC for flyback synchronous

rectification.

The main target of this design is to offer a high

power, cost-effective flyback converter for

notebook computer power supply with good

efficiency. This is achieved by using a quasi-

resonant PWM driver, synchronous rectification

and constant current driving of the ESBT switch.

The 240-400 VDC input range of the converter is

also tailored for PFC input use (not implemented

on the board). It is possible to use various PFC

conceptions based on other ST solutions.
