XDPE1A2G7B Description
The XDPE1A2G7B digital dual loop 16 phase controller provides power for nVIDIA AI servers, workstation, and high-end desktop GPU applications. Voltage on either the first loop or the second loop can be provided by a multi-phase buck converter with up to 16 synchronous-rectified channels on the first loop and up to 8 phases on the second loop. Typical configurations of 16+0, 15+1, and up to 8+8 are supported.
