The Texas Instruments TPS65311QRVJRQ1 is a specialized high-voltage, high-switching-frequency power management IC from the TPS65311-Q1 series, supplied in a 56-pin VQFN measuring 8 mm x 8 mm x 1 mm. It draws approximately 44 µA in operation and 60 µA quiescent, and is rated for -40°C to 125°C. The TPS65311QRVJRQ1 is lead free and RoHS compliant, carries an MSL 3 moisture sensitivity rating, and ships in 2, 000-piece tape and reel.

A multi-rail PMIC replaces several discrete regulators, references, and supervisory circuits with one device, which saves board area and simplifies the power-up and power-down sequencing that processors and radios require. A high input voltage capability means it can work directly from a nominal 12 V battery or industrial bus without a pre-regulator, and a low quiescent current keeps drain acceptable when the system is parked in standby. The 125°C rating and high pin count point to underhood, in-cabin, or enclosed industrial installations where ambient temperature is uncontrolled. Typical buyers are automotive tier-one suppliers and industrial equipment OEMs building infotainment, cluster, sensing, or control modules.
