TDA386400000AUMA1

TDA38640 is an easy-to-use, fully integrated and highly efficient OptiMOS™ IPOL single-voltage synchronous buck regulator 40A with SVID and I2C. 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: designed for Intel single phase power rails requiring SVID communication on platforms such as VR13HC and VR114, servers and high end desktop CPU VRs for non-core applications, telecom and datacom applications.
