The Texas Instruments TPS51117RGYTG4 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.
Key electrical specifications include a wide input voltage range from 1.8V to 28V and an output voltage range of 0.75V to 5.5V. The device boasts high efficiency with low power consumption, drawing only 4.5µA of shutdown current. Its fixed-frequency, emulated on-time control is adjustable from 100 kHz to 550 kHz, with a D-CAP mode providing a 100-ns load step response and less than 1% initial reference accuracy.
This controller supports selectable auto-skip/PWM-only operation for optimized efficiency at light loads or low-noise operation. It utilizes loss-less low-side RDS(on) sensing for current protection, including negative overcurrent limit. The TPS51117RGYTG4 integrates a boost diode, OVP/UVP, thermal shutdown, and a powergood signal. It also features internal soft-start and output discharge capabilities.
The TPS51117RGYTG4 is available in a 14-pin VQFN package with a surface mount type. It operates within a temperature range of -40°C to 85°C (TA).
