LMR34215FSC5RNXTQ1 TI Switching Regulator | 12-VQFN-HR (3x2) | 4.2V-42V Input, 1.5A Output

Product Overview

The LMR34215FSC5RNXTQ1 is a high-performance step-down (buck) switching regulator from Texas Instruments, designed for automotive and industrial applications. It operates over a wide input voltage range of 4.2V to 42V and delivers up to 1.5A of continuous output current. The device is housed in a compact 12-pin VQFN-HR package (3mm x 2mm), making it ideal for space-constrained designs. With integrated high-side and low-side MOSFETs, the LMR34215FSC5RNXTQ1 achieves high efficiency and simplifies PCB layout. It features a fixed 5V output voltage (FSC5 variant) and supports a switching frequency of 2.1 MHz, allowing for small external components.
