Description
General part information
STEVAL-ISA191V1 Series
The STEVAL-ISA191V1 evaluation board implements an isolated flyback double output (5 V / 1.2 A and 12 V / 0.75 A) 15 W wide range mains developed for general purpose applications.
The core of the application is the VIPer37LE, 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 evaluation board features a small size, minimal BOM, high efficiency and low standby consumption. Extremely low consumption under no-load conditions is ensured thanks to burst mode operation that reduces the average switching frequency and minimizes all frequency related losses.
