Description
General part information
STCMB1 Series
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.
It includes also a complete set of protections: a cycle-by-cycle overcurrent (OCP), an output overvoltage (OVP), a feedback failure (FFP, latch-mode), an ac brown-out, boost inductor saturation and inrush current detection both at the start-up and after mains sags or missing cycles.
