CQ1265RT datasheet

Description

In general, Quasi-Resonant Converter (QRC) shows lower EMI and higher power conversion efficiency compared to the conventional hard switched converter with a fixed switching frequency. Therefore, it is well suited for applications that are sensitive to the noise, such as color TV and audio. The CQ1265RT is an integrated Pulse Width Modulation (PWM) controller and Sense FET specifically designed for Quasi-resonant off-line Switch Mode Power Supplies (SMPS) with minimal external components.

Features

1. Optimized for Quasi-Resonant Converter (QRC)
2. Advanced Burst-Mode operation for under 1 W standby power consumption
3. Pulse by Pulse Current Limit (7A)
4. Over load protection (OLP) – Auto restart
5. Over voltage protection (OVP) – Auto restart
6. Abnormal Over Current Protection (AOCP) – Latch

Applications

1. CTV
2. DVD Receiver
3. Audio Power Supply
