STEVAL-ISA196V1 STMicroelectronics

STEVAL-ISA196V1 5 V / 1.2 A non-isolated flyback converter using VIPerPlus VIPer114LS Data brief Description The STEVAL-ISA196V1 evaluation board implements a flyback converter (5 V / 1.2 A) wide range mains developed for general purpose applications. The core of the application is the VIPer11, a new off-line high voltage converter from the VIPerPlus family. The device is a high-voltage converter that intelligently integrates an 800 V rugged power MOSFET with PWM current-mode control. Features The main characteristics of the evaluation board Universal AC main input voltage range: are its single layer, small size and minimal BOM, 85VAC to 265VAC high efficiency and low standby consumption. Output voltage: 5 V Output current: 1.2 A Rated output power: 6 W No load input power 230 VAC: < 10 mW Active mode efficiency: > 78% EMI: according to EN55022-Class-B RoHS compliant September 2017 DocID030970 Rev 1 1/4 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram STEVAL-ISA196V1 1 Schematic diagram Figure 1: STEVAL-ISA196V1 circuit schematic Output connector Input Connector 2/4 DocID030970 Rev 1 F1 BR Fuse 2.5 A IN RMB6S L1 D3 L2 2 T1 RV 4 2 4 5 Vpre Vout 1 Res Varistor 6 3.3H 470H OUT STPS5H100B C3 R5 C10 1 NTC C1 C2 1nF D1 C11 220k C9 2 R1 7 t Elcap 8.2F-400V Elcap 8.2F-400V 16ohm N.C. 2 8 470F-25V 1F 100F-25V MRA4007T3G ZLK - Rubycon TRANSFO No aux D2 R2 PGND N.C.
