TPS51611RHBR Description

Short technical summary and product information.

The Texas Instruments TPS51611RHBR is a fully IMVP-6.5 compliant single-phase, D-CAP+ mode step-down controller. It is engineered for CPU and Graphics VCORE applications, offering a conversion voltage range from 3V to 28V.

Key electrical specifications include a maximum output current of 60A, an output voltage range of 0.3V to 1.5V, and a typical quiescent current of 0.0018A. The controller operates with selectable frequencies of 250/300/350/500 kHz and features an 8-level selectable current limit. It boasts 0.5% V CORE accuracy over line, load, and temperature variations.

Designed for minimal external parts count, the TPS51611RHBR includes features like Power Good, VR_TT, and output current monitoring. It supports a 7-bit VID code for CPU and GPU power management. The device is available in a 32-pin, 5mm x 5mm QFN PowerPAD package, suitable for surface mounting.

This controller is optimized for efficiency at both light and heavy loads, with patented output overshoot reduction to minimize output capacitance requirements. The gate drivers have a 2A driving capability with an integrated boost diode.
