STEVAL-ISA180V1 STMicroelectronics

S T E VA L - I S A 1 8 0 V 1 12 V - 0.6 A flyback isolated converter using VIPer Plus VIPer0P Data brief Description The STEVAL-ISA180V1 evaluation board implements a wide mains range flyback isolated converter (12 V - 0.6 A), developed for general purpose applications. This high-voltage converter intelligently integrates an 800 V rugged power MOSFET with PWM current-mode control. The core of the application is the new VIPer0P off-line high voltage converter from VIPerPlus family with zero power features. The evaluation board features a small size and minimal BOM, high efficiency, low standby Features consumption and high reliability due to these protections: pulse skip mode to avoid flux- Universal AC main input voltage range: 85 to runaway, delayed overload protection (OLP), 265 VAC max duty cycle counter, VCC clamp and thermal Output range: 12 V - 0.6 A shutdown. Rated output power: 7.2 W Input power in standby 230 V : less than AC 18 mW Active mode efficiency: > 80% EMI: according to EN55022-Class-B RoHS compliant July 2016 DocID029568 Rev 1 1/4 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram STEVAL-ISA180V1 1 Schematic diagram Figure 1: STEVAL-ISA180V1 circuit schematic GSPG1807160955SG 2/4 DocID029568 Rev 1 R1 BR L1 L3 T1 IN D2 4 2 5 7 2 6 OUT 1 C8 + 1 C9 R2 + 2 C1 C2 + + C3 3 9 D1 2 10 R6 L2 D3 1 IC3 1 3 R7 2 4 C11 C10 R8 IC1 5 FB R9 6 IC2 COMP 3 C6 R10 R5 C7 R3 C5 C4 + D4 3 1 7 3 ON Vcc 8 OFF 2 13 Drain EAGND 14 Drain 4 15 Drain SGND 1 16 Drain PGND 1 2
