HR1211 Datasheet | Monolithic Power Systems

Multi-Mode PFC and Current Mode LLC Controller with Configurable Audible Noise Reduction Control DESCRIPTION The HR1211 is a multi-mode PFC and current mode LLC bo controller that is configurable via UART interface. Power-saving technology helps achieve optimized efficiency across the full operating range. The PFC controller employs a patented, digital average current control scheme to achieve hybrid CCM/DCM operation. Under heavy loads, CCM reduces the peak MOSFET current so the controller can be used across a wider load range. Under light loads, DCM reduces the switching frequency for better efficiency. Burst mode has configurable, digital soft switching to improve both...
