Datasheet for the Texas Instruments TPS51225, a 1.48 MB PDF. This part is a dual synchronous step-down controller with a 5 V LDO, widely used on notebook boards to produce the 3.3 V and 5 V system rails. The document gives pin functions, enable thresholds, power-good behaviour and a reference application circuit, which helps when a board has no always-on voltages or the controller runs hot. Compare the package marking code against the datasheet table to confirm the exact chip.
