STEVAL-ISA177V1 STMicroelectronics

STEVAL-ISA177V1 5 V, 0.85 A flyback converter using VIPer Plus VIPer01 Data brief Description The STEVAL-ISA177V1 evaluation board implements a wide-range converter in flyback non isolated topology, delivering 0.85 A on a 5 V output for general purpose applications. The core of the application is the new VIPer01 offline high voltage converter from the VIPerPlus range that intelligently integrates an 800 V rugged power MOSFET with PWM current-mode control. The main characteristics of the evaluation board are its single layer, small size with minimal BOM, high efficiency and low standby consumption. Features Universal AC main input voltage range: 85VAC to 265VAC Output range: 5 V / 0.85 A Rated output power: 4.25 W Input power in standby 230 V : < 9 mW AC Active mode efficiency: > 74% EMI: according to EN55022-Class-B RoHS compliant September 2016 DocID029259 Rev 2 1/4 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram STEVAL-ISA177V1 1 Schematic diagram Figure 1: STEVAL-ISA177V1 circuit schematic 2/4 DocID029259 Rev 2
