ICE5QR4780BG1XUMA1 Infineon AC-DC Controller | PG-DSO-12-24 | 800V Startup, Quasi-Resonant

Product Overview

The ICE5QR4780BG1XUMA1 is a highly integrated quasi-resonant flyback controller from Infineon's CoolSET™ family. It combines a 800V avalanche-rated CoolMOS™ startup cell with a PWM controller in a PG-DSO-12-24 package. This device is designed for high-efficiency AC-DC converters, offering low standby power (<100mW) and advanced protection features. The quasi-resonant operation reduces switching losses and EMI, making it ideal for applications requiring high power density and reliability.
