L4986 CCM PFC Controllers

STMicroelectronics L4986 CCM PFC Controllers are designed for boost converting and feature a proprietary multiplier “emulator.” This emulator, combined with the innovative THD optimizers, guarantees very low Total Harmonic Distortion (THD) performance in all operating conditions. Utilizing a proprietary off-time modulator, the L4986 operates in quasi-fixed frequency in all operating conditions with two options, 65kHz for A and 130kHz for B.
