Using ICE5AR4770BZS air conditioner 15W auxiliary SMPS

REF_5AR4770BZS_15W1

Overview

Using ICE5AR4770BZS air conditioner 15W auxiliary SMPS

This 15W auxiliary SMPS reference design supports wide-area input and is specifically developed for residential indoor air conditioning applications. It uses the new ICE5AR4770BZS PWM fixed frequency CoolSET™ with a 700V integrated MOSFET in a DIP-7 package.

Feature description

Flyback topology with single isolated output
100kHz switching frequency, discontinuous current mode design
90~264V AC wide range input
Output No. 1: 12V / 1.25A

Summary of advantages

The frequency decreases from medium load to light load and the efficiency is higher.

target application

Offline SMPS, adapters, set-top box main power supplies, water/air purifiers and TVs, air conditioner auxiliary power supplies, refrigerators, servers, PC power supplies and audio
