Description

  • STEVAL-ISA153V1, Evaluation Board implements a 12V/1.25A, 15W (20W 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. This device is a high-voltage converter that smartly integrates an 800V 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 VIPER38LE operates at a fixed 60 kHz frequency. Frequency jittering is implemented, which helps the application meet electromagnetic disturbance standards
