STMicroelectronics STCMB1, Power Factor & PWM Controller, 20 V, 75 kHz 20-Pin, SO
- RS庫存編號 175-1753
- 製造零件編號 STCMB1
- 製造商 STMicroelectronics
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
