LMR62421XSDX/NOPB

The LMR62421XSDX/NOPB from Texas Instruments is an easy-to-use, space-efficient 2.1A low-side switch regulator designed for Boost and SEPIC DC-DC regulation. It provides essential active functions for local DC/DC conversion, ensuring fast transient response and accurate regulation within a minimal PCB area.

This device operates with an input voltage range of 2.7V to 5.5V and can deliver an adjustable output voltage up to 24V. It features a switching frequency internally set at 1.6 MHz, which enables the use of very small surface mount inductors and capacitors, contributing to a tiny overall solution size and reduced system cost. The regulator includes features such as Enable, nonsynchronous rectification, cycle-by-cycle current limiting, and internal compensation.

Available in a compact 6-WSON (3x3 mm) package, the LMR62421XSDX/NOPB is suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ). The part also boasts low shutdown quiescent current of 80 nA and a maximum duty cycle of 96%.

This converter is fully enabled for WEBENCH Power Designer, aiding in the design process. Its performance benefits include extreme ease of use and a tiny overall solution, making it an ideal choice for applications requiring efficient and compact power management.
