## Description

The LM2621MM/NOPB from Texas Instruments is a high-efficiency step-up DC-DC switching regulator designed for battery-powered and low input voltage systems. It accepts an input voltage between 1.2V and 14V and converts it into a regulated output voltage that can be adjusted between 1.24V and 14V.

Key electrical specifications include a maximum load current of 1A, a switch current limit of 2.85A typical, and an internal 0.17Ω N-Channel MOSFET. The regulator can achieve efficiencies up to 90% and features a typical operating current of 80µA, with a supply current in shutdown less than 2.5µA.

The device operates over a temperature range of -40°C to 85°C. Its high switching frequency, adjustable up to 2 MHz, allows for the use of small surface mount inductors and capacitors, making it suitable for compact designs. The topology is a Boost converter, and it includes features like Enable and Nonsynchronous rectification.

Packaged in a VSSOP-8 surface mount package with a height of 1.09mm and a footprint of 14.7 mm², the LM2621MM/NOPB is designed for space-constrained applications.
