Productomschrijving
STMicroelectronics PWM Controller
The STMicroelectronics STCMB1 family is a 20V, 75kHz surface mount 20 pins PWM controller. This device is a transition mode (TM) PFC, a high voltage double-ended controller. It has an electrical rating of 800V with 6mA current. 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.
Features and Benefits
• Enhanced constant on-time PFC with input voltage feedforward, THD optimizer
• Half-bridge operation up to 750kHz with self-adjusting dead time
• Independent debug mode for both the converters
• It has a complete set of protection such as dc brown-out, two-level OCP, hard switching prevention (HSP) function for anti-capacitive mode protection and safe start-up
• It is LLC resonant combo controller
• Operation temperature ranges between -40°C and 85°C
• Proprietary time shift control for improved input ripple rejection and dynamic response
• Synchronous burst mode operation with PFC enhances light-load efficiency
• Half-bridge operation up to 750kHz with self-adjusting dead time
