Power Chips TPS65262RHBR

Product Short Description

The TI TPS65262RHBR is a highly integrated, monolithic power management IC featuring three synchronous step-down (buck) converters (3 A + 1 A + 1 A) and two adjustable low-dropout (LDO) linear regulators (200 mA + 100 mA). It supports a wide 4.5 V to 18 V input voltage range, ideal for space-constrained multi-rail applications requiring high efficiency and low quiescent power.
