The STCMB1 device embodies a transition mode (TM) PFC, a high voltage double-ended controller for LLC resonant half-bridge, an 800 V-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, thereby reducing the system cost and external component count.

800 V high voltage start-up with integrated

Active input filter capacitor discharge circuitry for reduced standby power

Independent debug mode for both converters

Enhanced constant on-time PFC with input voltage feedforward, THD optimizer

Complete set of protections: ac brown-in/out, inrush control, OVP, OCP, inductor saturation, feedback disconnection

Half-bridge operation up to 750 kHz with self-adjusting deadtime

(HSP) function for anti-capacitive mode

Synchronous burst mode operation
