DESCRIPTION

The TPS51511 is

350-kHz D-CAP-mode

–

Current Sensing From R_DS(ON)or Resistor

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

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.
