Infineon Technologies XDPS2221 | Demoboard REF_XDPS2221_140W1

Description

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

Features

• Digital combo controller for PFC and HFB in DSO-14 (150 mil) package
• Novel zero-voltage switching (ZVS) HFB topology for ultra-high system efficiency
• Integrated gate drivers supporting GaN and Si switches
• 600 V high-voltage start-up cell for fast VCC charging and active X-capacitor discharge
• Burst mode operation for lowest no-load standby power
• Adaptive PFC bus voltage and PFC enable/disable control to maximize average and light load efficiency
• Configurable parameters for protection modes and system performance
• Pb-free lead plating, halogen-free (according to IEC61249-2-21), RoHS compliant

Typical applications

• Adapters and chargers
