Product Summary

The TPS51117RG is a cost effective, synchronous buck controller for POL voltage regulation in notebook PC applications. The TPS51117RG is dedicated for Adaptive On-Time D-CAP Mode operation that provides ease of use, low external component count, and excellent fast transient response at the same time. Auto-skip mode for high efficiency down to the mill-ampere load range, or PWM-only mode for low noise operation is selectable. The applications of the TPS51117RG include Notebook Computers, I/O Supplies, and System Power Supplies.
