TPS51511 Description
The TPS51511 is a 350-kHz D-CAP-mode synchronous switcher with a 2-A, source-only low drop-out (LDO) regulator. It is specifically designed for low cost/low noise/low external-ponent count power systems for GPU applications. The integrated 'OD' switch in the buck controller supports dynamic output voltage change.
