XDPP1148-100B XDP™ integrated digital controller for DC-DC conversions with PWM and LLC support

概要

The XDPP1148-100B is the latest generation of digital controller product family. It adds close-loop LLC topology support, enhanced feed-forward, non-linear fast transient, light load power management and bi-directional configuration. The high-performance AFE, state-machine-based digital control loop, and Cortex®-M0 processor integrated in the 4x4 mm 24-pin VQFN package enables high power quality, low latency, and flexible power supply designs.
