STEVAL-ISA197V1 12 V, 7.8 W isolated flyback converter based on VIPer114LS Data brief Description The STEVAL-ISA197V1 evaluation board implements a 7.8 W (12 V / 0.65 A) isolated flyback wide range mains developed for general purpose applications. The core of the application is the innovative VIPer114LS IC, designed for smart power supplies incorporating green energy management. The device is a high-voltage converter that intelligently integrates an 800 V rugged power MOSFET with PWM current-mode control. VIPer114LS operates at fixed frequency 60 kHz Features with frequency jittering to meet standards Universal input mains range: 90 265VAC, regarding electromagnetic disturbance. The frequency: 50 60 Hz multiple protections on the device, including Output voltage: 12 V pulse skip mode to avoid flux-runaway, delayed Output current: 0.65 A overload, max duty cycle counter, input or output overvoltage and thermal shutdown improve the Very compact size reliability and safety of the design. Stand-by mains consumption: < 20 mW at 230V AC The main characteristics of the evaluation board Average efficiency: > 81% are its small size and minimal BOM, high EMI: according to EN55022-Class-B efficiency and low standby consumption. RoHS compliant Extremely low consumption under the no-load condition is ensured thanks to burst mode operation, which reduces the average switching frequency and minimizes all frequency-related losses.
