Product Description

DESCRIPTION
The TPS51219 is a small-sized single buck controller with adaptive on-time control. It provides a choice of control modes (D-CAP™ or D-CAP2™) to meet a wide range of system requirements. It is designed for tight DC regulation requirements such as the VCCIO application for Intel® notebooks. The performance and flexibility of the TPS51219 makes it suitable for low output voltage, high current, PC system power rails and similar point-of-load (POL) power supplies.
Differential voltage feedback and the voltage compensation function combine to provide high
precision power to load devices.
