TPS51117RGYR Description

Short technical summary and product information.

The Texas Instruments TPS51117RGYR is a cost-effective, synchronous buck controller designed for POL voltage regulation in notebook PC applications. It features the Adaptive On-Time D-CAP mode, which simplifies use, reduces external component count, and provides fast transient response.

 

Key electrical specifications include a wide input voltage range of 1.8V to 28V and an output voltage range of 0.75V to 5.5V. The controller supports up to 10A of output current and operates with a selectable switching frequency adjustable from 100 kHz to 550 kHz. It offers high efficiency with low power consumption, featuring a typical shutdown current of 4.5 µA. The D-CAP mode provides a 100-ns load step response and less than 1% initial reference accuracy.

 

Additional features include selectable auto-skip/PWM-only operation for efficiency or low-noise operation, temperature-compensated low-side RDS(on) sensing for overcurrent protection, and an integrated boost diode. The device also includes integrated OVP/UVP, thermal shutdown, a powergood signal, internal voltage soft-start, and integrated output discharge.

 

The TPS51117RGYR is available in a 14-pin VQFN package with a 3.5mm x 3.5mm body size. It is designed for surface mount applications and operates within an ambient temperature range of -40°C to 85°C.
