XDPE19283B - Infineon

XDPE19283B Digital Multi-phase Controller

The XDPE19283B digital dual loop 8 phase controller provides power for AMD™ SVI3 server, workstation, and high-end desktop applications. Core voltage is provided by a multi-phase buck regulator controlled by XDPE19283B that can be configured in one of the following phase combinations between the two loops: 8+0, 7+1, 6+2 ... 4+4. Command and monitor functions.
