Product details

Triple buck for multi-rail boards

The Texas Instruments TPS65250RHA is a three-channel step-down (buck) switching regulator with adjustable outputs, designed to generate multiple low-voltage rails from a single 4.5V to 18V input bus. Two outputs deliver up to 3A and one delivers up to 2A, making it a fit for powering the core, I/O, and auxiliary supplies in a system-on-module or multi-voltage peripheral board.

Output voltage range and switching flexibility

Each output can be set from a 0.8V reference up to 17.1V via external resistor dividers, covering the common 1.2V, 1.8V, 3.3V, and 5V logic rails as well as higher-voltage bias lines.
