LM5121MHX/NOPB TI Wide Vin Boost Controller | 20-HTSSOP | 3V-65V Input, 1.2MHz

Product Overview

The LM5121MHX/NOPB is a high-performance, wide input voltage range boost controller from Texas Instruments. It is designed for applications requiring efficient power conversion from a low-voltage source to a higher output voltage. The device operates from an input voltage range of 3V to 65V, making it suitable for automotive, industrial, and telecom systems. The LM5121 features a 1.2MHz fixed switching frequency, which allows for small external components and reduced solution size. It includes a high-side gate driver for synchronous rectification, enabling high efficiency over a wide load range. The device is available in a 20-pin HTSSOP package with an exposed pad for enhanced thermal performance.
