LM51581RTER TI DC-DC Converter | 16-WQFN (3x3) | 2.2MHz, 1.5A

Product Overview

The LM51581RTER from Texas Instruments is a high-performance, current-mode boost converter with an integrated 1.5A power switch. It operates at a fixed 2.2MHz switching frequency, enabling small external components and a compact solution size. The device supports input voltages from 2.7V to 15V and can generate output voltages up to 40V. It features a precision enable threshold, soft-start, and thermal shutdown for robust operation. Housed in a 16-pin WQFN (3x3mm) package, the LM51581RTER is ideal for space-constrained applications requiring high efficiency and reliability.
