FEATURES  
DESCRIPTION  
The LM3224 is a step-up DC/DC converter with a  
0.15Ω (typ.), 2.45A (typ.) internal switch and pin  
selectable operating frequency. With the ability to  
convert 3.3V to multiple outputs of 8V, -8V, and 23V,  
the LM3224 is an ideal part for biasing TFT displays.  
With the high current switch it is also ideal for driving  
high current white LEDs for flash applications. The  
LM3224 can be operated at switching frequencies of  
615kHz and 1.25MHz 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. An external soft-  
start pin allows the user to control the amount of  
inrush current during start up. The LM3224 is  
available in a low profile 8-lead VSSOP package.
