STEVAL-ISA136V1 STMicroelectronics

STEVAL-ISA136V1 3W, 5V output, isolated flyback converter using VIPer Plus - VIPER06HN Data brief Description The STEVAL-ISA136V1 evaluation board implements a 5 V / 0.6 A isolated flyback 3 W wide-range mains developed for general-purpose applications. The core of the application is the VIPER06HN, a new off-line high voltage converter from the VIPer plus family. The IC combines a high-performance low-voltage PWM controller chip and an 800 V, avalanche- rugged power MOSFET in the same package. The main characteristics of the board are its small size, high efficiency and low standby Features consumption. Extremely low consumption under no-load conditions is ensured thanks to burst Universal input mains range: 85 - 265 V AC mode operation, which reduces the average frequency: 50 - 60 Hz switching frequency and minimizes all frequency- Output voltage: 5 V / 0.6 A related losses. Very compact size The VIPER06HN operates at fixed frequency (115 Stand-by mains consumption: < 30 mW at kHz). Frequency jittering is implemented, helping 230 V it to meet electromagnetic disturbance standards. AC The device is equipped with protection features, Min active mode efficiency =66.89% AV such as delayed overload, open-loop failure and EMI: according to EN55022-Class-B hysteretic thermal protection, which improve the RoHS compliant reliability and safety of a design.
