STEVAL-ISA111V1: 12 V / 12 W, 115 kHz non-isolated flyback

Overview

TopologyFlyback Converter
Input voltage90-265 V
Output 112 V / 1 A
IC revision1

Description

The STEVAL-ISA111V1 demonstration board is a 12 V, 1 A power supply set in non-isolated flyback topology using the VIPER26HN, the new offline high voltage converter by STMicroelectronics.The features include an 800 V avalanche rugged power section, PWM operation at 115 kHz with frequency jittering for lower EMI, current limiting with adjustable set point, onboard soft-start, a safe auto-restart after a fault condition and a low standby power. The protections include thermal shutdown with hysteresis, delayed overload protection, and open loop failure protection.

Features

◾Universal input mains range: ◾input voltage 90 - 264 VAC◾frequency 45 - 65 Hz

◾Single-output voltage: 12 V at 1 A continuous operation◾Standby mains consumption: < 30 mW at 230 VAC◾Average efficiency: > 80%◾Fully protected against faults (overload, feedback disconnection and overheating)◾EMI: according to EN55022-Class-B◾RoHS compliant
