HR1215 Multi-Mode PFC and Current Mode LLC Controller without Shutdown during X-Capacitor Discharge Period DESCRIPTION The HR1215 is a multi-mode PFC and current mode LLC combo controller that is configurable via a UART interface. Power-saving technology optimizes efficiency across the entire operating range. The PFC controller employs a patented, digital average current control scheme to achieve hybrid continuous conduction mode and discontinuous conduction mode (CCM/DCM). At heavy loads, CCM reduces the peak MOSFET current so that the controller can be used across a wider load range. At light loads, DCM reduces the switching frequency (fSW) for improved efficiency. Burst mode has configurable, digital soft switching that can improve both light-load efficiency and audible noise.
