LM2623 - DC/DC Boost Converter

Download the LM2623 datasheet PDF. This datasheet also covers the LM2 variant, as both devices belong to the same dc/dc boost converter family and are provided as variant models within a single manufacturer datasheet.

General Description

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

It accepts an input voltage between .8 and 14 volts and converts it into a regulated output voltage between 1.24 and 14 volts.

LM2623 General Purpose, Gated Oscillator Based, DC/DC Boost Converter July 2003 LM2623 General Purpose, Gated Oscillator Based, DC/DC Boost Converter General Description The LM2623 is a high efficiency, general purpose, step-up DC-DC switching regulator for battery-powered and low input voltage systems. It accepts an input voltage between .8 and 14 volts and converts it into a regulated output voltage between 1.24 and 14 volts. Efficiencies up to 90% are achievable with the LM2623. In order to adapt to a number of applications, the LM2623 allows the designer to vary the output voltage, the operating frequency (300kHz to 2 MHz) and duty cycle (17% to 90%) to optimize the part’s performance. The selected values can be fixed or can vary with battery voltage or input to output voltage ratio.
