STEVAL-ISA022V1

STEVAL-ISA022V1 6 W isolated flyback topology power supply evaluation board based on VIPer12A-E Data Brief 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 ) s ( ct u d o Description r P e 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 buckconverter 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. t e l o ) (s s b O t c u STEVAL-ISA022V1 d o r P e t e l o s b O December 2007 Rev 2 For further information contact your local STMicroelectronics sales office. 1/4 www.st.com 4 Board schematic 1 STEVAL-ISA022V1 Board schematic Figure 1.
