CoolSET™ PWM quasi-resonant

High-performance PWM quasi-resonant flyback ICs for AC-DC power conversion

Overview

Infineon's CoolSET™ PWM quasi-resonant controller offers high performance and a complete suite of protection to increase system robustness in AC-DC power conversion. Novel QR quasi-resonant (patent pending) switching limits the spread of switching frequency between high/low line input and thus lowers the EMI signature. Designers can lower system design costs by using higher switching frequencies and smaller magnetics.
