LM5158QRTERQ1 TI Switching Controller | 16-WQFN (3x3) | 2.2MHz, 40V

Product Overview

The LM5158QRTERQ1 is a high-performance, automotive-grade non-synchronous boost controller from Texas Instruments. It is designed to provide a compact and efficient power solution for a wide range of applications, including automotive, industrial, and telecommunications. With a wide input voltage range of 2.2V to 40V, it can operate from single-cell Li-Ion batteries up to 40V automotive rails. The device features a 2.2MHz fixed switching frequency, allowing for small external components and reduced solution size. Its integrated 40V, 1.5A power switch enables high output voltages up to 40V, making it suitable for boost, SEPIC, and flyback topologies.
