TPS51285ARUKT

TPS51285ARUKT Description

The TPS51285ARUKT from Texas Instruments is a highly integrated quad-output power management IC (PMIC) designed for precision voltage regulation in demanding applications. This surface-mount device combines two buck controllers and two linear regulators (LDOs) in a compact 20-pin WQFN package, making it ideal for space-constrained designs. Operating from a wide input voltage range of 5V to 24V, it delivers stable power with switching frequencies of 400kHz or 475kHz, optimizing efficiency and reducing external component count. The ROHS3-compliant and REACH-unaffected device ensures environmental compliance, while its MSL 1 (Unlimited) rating guarantees reliability in storage and handling.
