Product overview

Description

The STEVAL-ISA184V1 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 VIPer37LD 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 small size and minimal BOM, high efficiency and low standby consumption. Extremely low consumption under no-load conditions is ensured thanks to burst mode operation, which reduces the average switching frequency and minimizes all frequency-related losses.

The VIPer37LD operates at 60 kHz fixed frequency, and frequency jittering is implemented to help meet the standards regarding electromagnetic disturbance. The several protections on the device like overvoltage, overload, output short circuit, secondary winding short, hard transformer saturation protection and brown out protections improve the safety and reliability of the design.
