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.
