TPS51117PWG4 Description

Short technical summary and product information.

The TPS51117PWG4 from Texas Instruments is a cost-effective, synchronous buck controller designed for POL voltage regulation in notebook PC applications. It features Adaptive On-Time D-CAP mode, offering ease-of-use, a low external component count, and fast transient response.

 

This controller supports a wide input voltage range from 1.8V to 28V and can regulate output voltages from 0.75V to 5.5V. It offers selectable auto-skip mode for high efficiency at light loads or PWM-only mode for low-noise operation. The device utilizes loss-less low-side RDS(on) sensing for current protection.

 

Available in a 14-pin TSSOP package, the TPS51117PWG4 is suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. Key control features include Enable, On Time Control, and Power Good signals.
