REF_5QR1070AZ_33W1 Auxiliary SMPS Reference Design for Refrigerators

REF_5QR1070AZ_33W1

Overview

The REF_5QR1070AZ_33W1 auxiliary SMPS reference design for refrigerators operates over a wide range of inputs and was developed with offline SMPS applications in mind. Using dual isolated outputs, the +12V rail powers the relay, while the +5V rail powers the MCU and various sensors. It adopts the new ICE5QR1070AZPWM quasi-resonant flyback, equipped with 700V integrated CoolSET™, and adopts DIP-7 package.

Feature description

Dual output isolated flyback technology
85~300V _AC wide range input
Output No. 1: 12V / 2.66A
Output No. 2: 5V / 0.2A

Advantage

High efficiency quasi-resonant switch
Cost-effective solution that provides stable protection against line failures

Potential applications

Offline SMPS
adapter
Main power supply for set-top boxes, water purifiers/air purifiers and TVs
Auxiliary power supply for air conditioners, refrigerators, servers, PC power supplies and speakers
