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.
