   产品概述 返回TOP21S嘉泰姆

The CXLE87156 is a single stage Flyback and PFC controller targeting at LED lighting applications with PWM/Analog dimming. It is a primary side controller without applying any secondary feedback circuit for low cost, and drives the Flyback converter in the quasi-resonant mode to achieve higher efficiency. It keeps the Flyback converter in constant on time operation to achieve high power factor.
