ICE5QR4780BGXUMA1 Infineon AC-DC Controller | PG-DSO-12-21 | 800V Startup, 65kHz

Product Overview

The ICE5QR4780BGXUMA1 is a high-performance AC-DC PWM controller from Infineon's CoolSET™ Quasi-Resonant family. It integrates a 800V startup cell, a current mode PWM controller, and a 650V CoolMOS™ power MOSFET in a compact PG-DSO-12-21 package. This device is designed for flyback converters operating in quasi-resonant (QR) mode, enabling high efficiency and low EMI across a wide load range. The controller features frequency reduction for light load efficiency, burst mode for standby power reduction, and comprehensive protection functions including auto-restart, overvoltage, and overtemperature protection.
