The Texas Instruments TPS51117RGYT 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 1.8 V to 28 V and supports an output voltage range of 0.75 V to 5.5 V.
This controller utilizes the Adaptive On-Time D-CAP mode, offering ease-of-use, a low external component count, and fast transient response. It provides selectable Auto-skip mode for high efficiency at light loads or PWM-only mode for low-noise operation. Key electrical features include a typical shutdown current of 4.5 μA, adjustable switching frequency from 100 kHz to 550 kHz, and a load step response of 100 ns in D-CAP mode.
The TPS51117RGYT is available in a 14-pin VQFN package with surface mount mounting type. It operates within a temperature range of -40°C to 85°C. The device includes features such as Enable, On Time Control, and Power Good signals, along with integrated overvoltage protection (OVP), undervoltage protection (UVP), and thermal shutdown.
Applications for this controller include notebook computers, I/O supplies, and general system power supplies.
