同步切换控制器， 2 -A LDO的GPU电源 Synchronous Switcher Controller With 2-A LDO for GPU Power
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-component count power systems for GPU applications. The integrated "OD" switch in the buck controller supports dynamic output voltage change. The current mode option of the synchronous buck converter can support pure output ceramic-capacitor applications. The open-drain LDO power-good signal can be accessed through the OD pin when it is needed in the application. The TPS51511 is available in the thermally-enhanced 20-pin QFN package, and is specified from -40°C to 85°C.
