LM2621 - Step-Up DC-DC Converter

General Description

The LM2621 is a high efficiency, step-up DC-DC switching regulator for battery-powered and low input voltage systems.

It accepts an input voltage between 1.2 V and 14 V and converts it into a regulated output voltage.

The output voltage can be adjusted between 1.24 V and 14 V.
