The TPS51217DSCR from Texas Instruments is a compact, single synchronous step-down (buck) controller. It is designed for low output voltage, high current applications, such as PC system power rails and point-of-load power supplies in digital consumer products.
This controller features a wide input voltage range of 3V to 28V and supports output voltages from 0.6V to 2.6V, with a high output current capability of up to 20A+. It utilizes D-CAP mode with a fast 100ns load step response and adaptive on-time control architecture operating at a fixed 340kHz frequency.
The TPS51217DSCR is available in a 10-pin WSON package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. The device includes features like Enable and Power Good signals, internal soft-start, and built-in output discharge.
Key electrical characteristics include a 0.6V internal reference voltage and low-side FET R DS(on) current sensing for efficient operation over a broad load range. The design prioritizes space saving on the PCB with a minimal pin count.
