General Description

The TPS53819A device is a small-sized, single buck controller with adaptive on-time D-CAP2 mode control and PMBus.

The device is suitable for low output voltage and high current, system power rail, or similar point-of-load (POL) power supply in digital consumer products.

Small package with minimal pin-count saves space on the PCB, while the programmability and fault report via PMBus simplify the power supply design.
