STMicroelectronics 5 V / 1.2 A Non-Isolated Flyback Converter using VIPerPlus VIPer114LS Flyback Converter for

STMicroelectronics provides turnkey solutions that address the growing demand for innovation to reach higher efficiency, higher power density and lower standby power designs. This is achieved through a wide range of power discrete components, analog ICs and digital processors.

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. The main characteristics of the evaluation board are its single layer, small size and minimal BOM, high efficiency and low standby consumption.
