LM5176RHFT TI Power Management IC | 28-VQFN (5x4) | 4.5V-55V, 3.5A

Product Overview

The LM5176RHFT is a versatile synchronous buck-boost controller from Texas Instruments, designed to regulate output voltage over a wide input voltage range. It operates from 4.5V to 55V and supports output voltages from 0.8V to 55V, making it ideal for applications requiring stable power despite fluctuating input sources. The device integrates four N-channel MOSFET drivers and provides seamless transition between buck, boost, and buck-boost modes. Housed in a compact 28-pin VQFN (5x4) package, it offers high efficiency and thermal performance.
