LM2621 Datasheet (National Semiconductor) - Low Input Voltage/ Step-Up DC-DC Converter

LM2621, Low Input Voltage/ Step-Up DC-DC Converter

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 1.2V and 14V and converts it into a regulated output voltage.

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

It has an internal 0.17Ω N
