TPS51117 General Description

The TPS51117 is a cost effective, synchronous buck controller for POL voltage regulation in notebook PC applications. The controller 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 milli-ampere load range, or PWM-only mode for low noise operation is selectable.

The current sensing scheme for positive overcurrent and negative overcurrent protection is loss-less low-side RDS(on) sensing plus temperature compensation. The device receives 5-V (4.5 V to 5.5 V) supply from another regulator such as the TPS51120 or TPS51020 in the NBPC system. The conversion input can be either VBAT or 5-V rail,ranging from 1.8 V to 28 V, and the output voltage range is from 0.75 V to 5.5 V.

The TPS51117 is available in the 14-pin TSSOP package and is specified from 40°C to 85°C.
