Beschreibung

The XDP™ XDPS2221 controller is a highly integrated device including the valley-switching PFC controller, the HFB (asymmetrical half-bridge) controller and three gate drivers for the main switches. The internal handshaking between the PFC and HFB controller and the adaptive bus voltage setting make this controller a perfect fit for applications with wide AC input and wide output voltage range, such as USB-PD adapters and battery chargers. While detailed information about this control IC can be found in the product datasheet [1], here is a short summary of the product highlights, the main features, the IC pin layout and the main benefits for the customer
