TPS51219RTER 3D Model
The TPS51219RTER is a small-sized single buck controller with adaptive on-time control. It provides a choice of control modes (D-CAPTM or D-CAP2TM ) to meet a wide range of system requirements. It is designed for tight DC regulation requirements such as the VCCIO application for IntelP notebooks. The performance and flexibility of the TPS51219RTER make 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.
The TPS51219RTER is available in a 16 -pin, QFN package and is specified for ambient temperature from -40 °C to 85 °C
