Infineon Technologies XDP™ XDPP114x Digital Power Controllers
Infineon Technologies XDP™ XDPP114x Digital Power Controllers are designed for AC/DC and DC/DC power converters. The Infineon Technologies XDP XDPP114x features a high-performance analog front end and optimized power-processing digital blocks. These controllers come with pre-integrated firmware to reduce development efforts.
The devices' state machine-based control loop architecture supports various operating modes, including PWM and PFM modulation, voltage mode, and peak current mode control. Equipped with a 32-bit, 100MHz ARM® Cortex®-M0 RISC microcontroller, the XDPP114x enables enhanced control, real-time monitoring, peripheral configuration, and communication management. Additional capabilities include firmware customization for sequencing, black box data recording, and interfacing.
