High Efficiency, Low Power Consumption,  
4.5-μA Typical Shutdown Current  
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 fast  
transient response. Auto-skip mode for high efficiency  
down to the milli-ampere load range, or PWM-only  
mode for low noise operation is selectable.  
Fixed Frequency Emulated On-Time Control,  
Adjustable from 100 kHz to 550 kHz  
D-CAP™ Mode with 100-ns Load Step

< 1% Initial Reference Accuracy  
Output Voltage Range: 0.75 V to 5.5 V  
Wide Input Voltage Range: 1.8 V to 28 V  
Selectable Auto-Skip/PWM-Only Operation  
The current sensing scheme for positive overcurrent  
and negative overcurrent protection is loss-less

Temperature Compensated (4500 ppm/°C)  
Low-Side RDS(on) Overcurrent Sensing  
compensation. The device receives a 5-V (4.5 V to  
5.5 V) supply from another regulator such as the  
TPS51120 or TPS51020. The conversion input can  
be either VBAT or a 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 a 14-pin QFN or a  
14-pin TSSOP package and is specified from –40°C  
to 85°C.
