STCMB1TR, SO-20 AC-DC Controllers & Regulators

STCMB1 Transition Mode (TM) PFC STMicroelectronics STCMB1 Transition Mode (TM) PFC features a high voltage double-ended controller, 800V-rated high voltage section and the glue logic that supervises the operation of these three blocks. The PFC section uses a proprietary constant on-time control methodology that does not require a sinusoidal input reference. This reduces the system cost and external component count. STMicroelectronics STCMB1 Transition Mode (TM) PFC has active input filter capacitor discharge circuitry for reduced standby power, compliant with IEC 62368-1 and UL Demko certified.
