LM2621MMX Description

Short technical summary and product information.

The LM2621MMX from Texas Instruments is a versatile 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, converting it to a regulated output voltage that can be adjusted from 1.24V to 14V.

 

Key electrical specifications include a switch current limit of 2.85A (typical), a switching frequency adjustable up to 2MHz, and an internal 0.17Ω N-Channel MOSFET. This device can achieve efficiencies of up to 90% and supports a load current of up to 1A. Its typical operating current is 80µA, with a shutdown current of less than 2.5µA.

 

The LM2621MMX features an 8-VSSOP package, suitable for surface mounting. It operates within an ambient temperature range of -40°C to 85°C. The high switching frequency capability allows for the use of small surface-mount inductors and capacitors, making it ideal for space-constrained applications.
