STEVAL-ISA022V1
6 W isolated flyback topology power supply evaluation board
based on VIPer12A-E
Features
■Input voltage range: from 90 to 264 VAC
■Input voltage frequency range: 50/60 Hz
■Main output (regulated): 5 V/500 mA
■Second output: 15 V/ 200 mA
■Total maximum output power: 5.5 W
Description
This evaluation board is a power supply solution
based on an offline discontinuous current mode
flyback converter with isolated input and output.
The flyback topology fully exploits the current and
voltage capability of the incorporated monolithic
VIPer12A-E device when compared with a buck-
converter based power supply. The VIPer12-E
incorporates a PWM controller with a 60 kHz
internal oscillator and a vertical Power MOSFET
switch in an SO-8 package.
