LM2622  
600kHz/1.3MHz Step-up PWM DC/DC Converter  
n 600kHz/1.3MHz pin selectable frequency operation  
n Over temperature protection  
n 8-Lead MSOP package  
General Description  
The LM2622 is a step-up DC/DC converter with a 1.6A, 0.2  
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 MSOP package.  
Applications  
n TFT Bias Supplies  
n Handheld Devices  
n Portable Applications  
n GSM/CDMA Phones  
n Digital Cameras  
Features  
n 1.6A, 0.2, internal switch  
n Operating voltage as low as 2.0V  
Typical Application Circuit  
10127331  
600 kHz Operation
