STMicroelectronics STEVAL-ISA191V1 Evaluation Board
STMicroelectronics STEVAL-ISA191V1 Evaluation Board implements an isolated flyback double output (5V/1.2A and 12V/0.75A) 15W wide range mains developed for general-purpose applications. The application's core is the VIPer37LE off-line high voltage converter from the VIPerPlus family. This STMicroelectronics device is a high-voltage converter that intelligently integrates an 800V rugged power MOSFET with PWM current-mode control.
The evaluation board features a small size, minimal BOM, high efficiency, and low standby power consumption. The STEVAL-ISA191V1 ensures extremely low consumption under no-load conditions through burst mode operation, reducing the average switching frequency and minimizing all frequency-related losses.
