  • The STEVAL-ISA153V1 product evaluation board implements a 12 V/1.25 A, 15 W (20 W peak) isolated flyback wide-range mains developed for general-purpose applications.

    The core of the application is the VIPER38LE, the latest offline converter from the VIPerPlus family. The device is a high-voltage converter that smartly integrates an 800 V rugged power MOSFET with PWM current-mode control. The device features an adjustable extra power timer (EPT) that enables the IC to sustain overload conditions for a few seconds.
    The main characteristics of the evaluation board are its small size and minimal BOM, high efficiency and low standby consumption. Extremely low consumption under no-load conditions is ensured thanks to burst mode operation which reduces the average switching frequency and minimizes all frequency-related losses.
    The VIPER38LE operates at a fixed 60 kHz frequency. Frequency jittering is implemented, which helps the application meet electromagnetic disturbance standards.
    The IC includes high-level protection features such as dual-level OCP, output overvoltage, short-circuit, and thermal shutdown with hysteresis. After removal of a fault condition, the IC is automatically restarted.

    主要特性

    • Universal input mains range: 90 – 265 VACfrequency: 50 - 60 Hz
    • Output voltage/current: 12 V/1.25 A (1.65 A peak)
    • Very compact size
    • Standby mains consumption: lower than 30 mW at 230 VAC
    • Minimum active mode efficiency: 81.55%
    • Minimum active mode at 10% load efficiency: 71.55%
    • EMI: in accordance with EN55022-Class-B
    • RoHS compliant
