LM2623 Datasheet (Texas Instruments)

LM2623, DC-DC Boost Converter

The LM2623 is a high-efficiency, general-purpose, step-up DC-DC switching regulator for batterypowered and low input voltage systems.

It accepts an input voltage between 0.8 V and 14 V and converts it into a regulated output voltage between 1.24 V and 14 V.

Efficiencies up to 90% are achievable with
