FEATURES  
DESCRIPTION  
The LM2622 is a step-up DC/DC converter with a  
1.6A, 0.2Ω internal switch and pin selectable  
operating frequency. With the ability to convert 3.3V  
to multiple outputs of 8V, -8V, and 23V, the LM2622  
is an ideal part for biasing TFT displays. The LM2622  
can be operated at switching frequencies of 600kHz  
and 1.3MHz allowing for easy filtering and low noise.  
An external compensation pin gives the user flexibility  
in setting frequency compensation, which makes  
possible the use of small, low ESR ceramic  
capacitors at the output. The LM2622 is available in a  
low profile 8-lead VSSOP package.
