LM2621 Description

Short technical summary and product information.

The LM2621 from Texas Instruments is a versatile step-up DC-DC switching regulator. It is engineered for applications requiring efficient power conversion from low input voltages, such as battery-powered devices. The regulator accepts an input voltage range of 1.2V to 14V and can deliver an adjustable output voltage between 1.24V and 14V.

Key features include a high switching frequency, adjustable up to 2 MHz, which enables the use of small surface-mount inductors and capacitors, contributing to a compact design. It boasts up to 90% regulator efficiency and an internal 0.17-Ω N-Channel MOSFET power switch. The device also offers a low operating current of 80 µA and a shutdown current of less than 2.5 µA, making it suitable for power-sensitive applications.

The LM2621 is available in a VSSOP-8 package, which is half the footprint of a standard 8-pin SOIC package and has a low profile of 1.09 mm. This small package size and low height are advantageous for space-constrained designs.

Typical applications for the LM2621 include PDAs, cellular phones, 2-cell and 3-cell battery-operated equipment, PCMCIA cards, memory cards, flash memory programming, and TFT/LCD displays.
