Based on CM6900 Resonance IC Controller SRC LED Lamp Driver Circuit

Abstract:

CM6900 is a kind of built-in synchronous rectifier drivers, OVP / OCP, and better soft-start mode, while a FM + PWM operation mode of the resonant controller IC, and its application in the constant current / constant voltage mode is very easy. Based CM6900's 90W SRC LED lamp drive circuit relative to the LLC drive circuit is easier to implement synchronous rectification, Efficiency (greater than or equal to 0.94), transformer design is simple (standard BOBBIN reduce mold costs).
