LMR62421XMF

The LMR62421XMF from Texas Instruments is an easy-to-use, space-efficient 2.1A low-side switch regulator ideal for Boost and SEPIC DC-DC regulation. It provides essential active functions for local DC/DC conversion, offering fast transient response and accurate regulation within a minimal PCB area.

This boost converter features an input voltage range of 2.7V to 5.5V and can deliver an output voltage up to 24V, with a switch current limit typically at 3A and a maximum switch current of 2.1A. The internal switching frequency is set at 1.6 MHz, enabling the use of small surface-mount inductors and capacitors, contributing to a tiny overall solution size and reduced system cost.

Key electrical characteristics include a typical quiescent current of 0.007A and a low shutdown current of 80 nA. The device operates within an ambient temperature range of -40°C to 125°C. It supports features such as enable functionality, nonsynchronous rectification, cycle-by-cycle current limiting, internal compensation, and internal soft-start.

The LMR62421XMF is available in a 5-pin SOT-23 package (2.92 mm x 2.84 mm) and a 6-pin WSON package (3 mm x 3 mm). Its design prioritizes ease of use and a compact footprint, making it suitable for various power management applications where space and performance are critical.
