TPS51117PWR Description

Short technical summary and product information.

The Texas Instruments TPS51117PWR is a cost-effective, synchronous buck controller designed for POL voltage regulation in notebook PC applications. It operates with a wide input voltage range from 1.8V to 28V and supports an output voltage range of 0.75V to 5.5V.

 

This controller utilizes D-CAP mode for ease of use, a low external component count, and fast transient response. It offers selectable Auto-skip or PWM-only operation for efficiency at light loads or low-noise operation, respectively. Key electrical features include a typical shutdown current of 4.5µA, adjustable frequency from 100 kHz to 550 kHz, and a 100-ns load step response.

 

The TPS51117PWR is available in a 14-TSSOP package and operates within a temperature range of -40°C to 85°C. It includes integrated features such as overvoltage protection (OVP), undervoltage protection (UVP), thermal shutdown, and a powergood signal.
