M0L1228QRHBRQ1 TI Automotive Buck Converter | 32-VQFN (5x5) | 2.2MHz, 3A Output

Product Overview

The M0L1228QRHBRQ1 is a high-performance automotive-grade step-down (buck) converter from Texas Instruments, designed for space-constrained power management applications. Housed in a compact 32-VQFN (5x5 mm) package, this device delivers up to 3A continuous output current with excellent efficiency. It operates over a wide input voltage range of 3.5V to 36V, making it suitable for 12V and 24V automotive battery systems. The device integrates high-side and low-side MOSFETs, reducing external component count and simplifying PCB layout.
