(From User Guide) The purpose of this document is to provide information on the STEVAL-ISA081V1 switched mode power supply (SMPS) demonstration board. The STEVAL-ISA081V1 is an isolated SMPS capable of delivering a 12 W output over a wide input voltage range. It is designed for a mains application focused on providing a cost-effective and space-saving solution.

This demonstration board is based on the new VIPer17H device, that is a converter that offers in one package a PWM controller built in BCD6 technology and a 800 V avalanche rugged vertical power section.

This board is an off-line wide range dual output general-purpose power supply capable of delivering up to 24W through two outputs, +5V and +12V. The board is configured for secondary regulation with optocoupler feedback.

The aim of the presented reference boards is to propose a power supply solution based on an offline discontinuous current mode flyback converter with isolation between input and output. The VIPer12AS incorporates the PWM controller with 60 kHz internal oscillator and altogether with the vertical power MOSFET switch in a SO8 package.

This evaluation board is an offline, wide-range, VIPer22A-E dual-output power supply with a switching frequency of 60 kHz and is set up for secondary regulation with an optocoupler. One output delivers 5 V at 1 A and a second output delivers 12 V at 0.42 A, making for a total output power of 10 W.

This document is an engineering report describing a 1.25A, 12V and 0.5A, 5V dual output embedded power supply utilizing the INN2904K, with a 900 V rated MOSFET, from the InnoSwitch-EP family of ICs.

The STEVAL-ISA183V1 evaluation board implements a 16 W triple output power supply designed in quasi-resonant flyback topology,

This document describes the STEVAL-ISA010V1 demonstration board, which is designed as an example of a simple non-isolated auxiliary power supply for a range of input voltages from 85 VAC to 500 VAC. There is an ever-increasing demand for small power supplies capable of working without voltage range limitations, even at nominal levels of 400 VAC and 415 VAC, respectively.

This demonstration board introduces a solution for industrial power supplies. It takes advantage of the high voltage Power MOSFET, i.e. 1500 V breakdown voltage, to optimize the operation of the flyback converter based on the primary controller UC3844B.
