FEATURES  
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.

1.1V Start-up Voltage  
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. The LM2623 uses  
a very simple, on/off

regulation mode to produce good efficiency and  
stable operation over a wide operating range. It  
normally regulates by skipping switching cycles when  
it reaches the regulation limit (Pulse Frequency  
Modulation).
