HR1213 Datasheet | Monolithic Power Systems

Multi-Mode PFC and Current Mode LLC bo Controller Supporting both AC and DC Inputs with Configurable Bias Options DESCRIPTION The HR1213 is a multi-mode PFC and current mode LLC bo controller that can be configured via the UART interface. Powersaving technology helps the device optimize efficiency across the full operating range. The PFC controller employs a patented, digital average current control scheme to achieve hybrid continuous conduction mode (CCM) and discontinuous conduction mode (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...
