TDA38725 is an easy-to-use, fully integrated and highly efficient OptiMOS� IPOL single-voltage synchronous buck regulator 25A with PMBus interface. This can be used for intel VR12, VR 12.5, VR13, VR14, IMPVP8 designs and DDR memory without significant changes to the bill of materials (BOM). The required mode is selected in MTP and the pin-out, VID table and other relevant functions are automatically configured. This greatly reduces time-to-market and eliminates the need to manage and inventory different PWM controllers. The device configuration can be easily defined using Infineon's XDP� Designer GUI and is stored in the on-chip memory. Potential applications are telecom and datacom, base stations, FPGA power, storage, server, distributed point of load power architectures.
