REF_XDPS2222_240W1 XDP™ XDPS2222: PFC + hybrid flyback combo IC for 240 W USB PD form factor reference design
Overview
Infineon's REF_XDPS2222_240W1 is a high efficiency form-factor reference design, with 25 W/in3 power density, using XDP™ XDPS2222 PFC + hybrid flyback (HFB) digital combo IC.
The internal handshaking between the PFC and HFB controller and the adaptive bus voltage setting makes this controller perfect for applications with wide AC input and very wide output voltage range, such as USB PD extended power range (EPR) adapters and battery chargers.
Summary of Features
- HFB ZVS operation of high- and low-side
- Fast responding HFB peak current control
- Harmonized PFC & HFB operations
- Pulse skipping at light load
- Automatic PFC enable/disable control
- Self-adjusting PFC bus voltage level
Benefits
- High efficiency over wide range
- High power density
- Extra-wide output voltage range
- Low no-load input standby power
- Enables high power density designs
- Low external BOM cost and count
- Configurable design with GUI tools
