TPS51219RTER Description

The TPS51219RTER is a single buck controller with adaptive on-time control that is modest in size. It offers two control modes (D-CAPTM or D-CAP2TM) to accommodate a variety of system requirements. It is made to meet stringent DC regulation specifications, such as those of the VCCIO application for Intel? laptop computers. The TPS51219RTER's functionality and adaptability make it appropriate for point-of-load (POL) power supply with low output voltage, high current, and PC system power rails. The voltage compensation mechanism and differential voltage feedback work together to deliver high accuracy power to load devices.
