Below is the links of new app notes that your product are used and this is the last product for this family “fifth generation QR CoolSET and Controller”ICE5QR1070AZhttps://www.infineon.com/dgdl/Infineon-ApplicationNote_ReferenceDesign_REF_5QR1070AZ_33W-AN-v01_00-EN.pdf?fileId=5546d4625ee5d4cd015ef0fceacd2654AN_201702_PL83_00833W Auxiliary SMPS for refrigerator usingREF_5QR1070AZ_33W1This document is an engineering report that describes a universal-input 24 W 12 V and 5 V off-line flybackconverter using the newest 5th generation Infineon quasi resonant CoolSET™ ICE5QR2270AZ. It offers highefficiency,low-standby power with selectable entry and exit standby power options, a wider VCC operating range with fast start-up, robust line protection with input Over Voltage Protection (OVP), and brownout and various modes of protection for a highly reliable system. This demo board is designed for users who wish to evaluate the performance of ICE5QR2270AZ and its ease of use.

Merkmale

  • Novel quasi-resonant switching scheme•Rapid and adjustable start-up with cascode configuration•2 level selectable active burst mode level•Built-in digital soft-start•Cycle by cycle peak current limitation•Digital frequency reduction with decreasing load for higher efficiency•Adjustable line input over-voltage and brown IN/OUT protection•VCC and CS pin short to ground protection•OLP, output short, output over-voltage, OTP with hysteresis and VCC over/under voltage protection•Auto-restart for all protection features
