3-Channel DC/DC Converter  
Features  
• TFT-LCD display supply  
- Boost regulator  
The EL7583 is a 3-channel DC/DC converter IC which is  
designed primarily for use in TFT-LCD applications. It  
features a PWM boost converter with 2.7V to 14V input  
capability and 5V to 17V output, which powers the column  
drivers and provides up to 470mA @ 12V, 370mA @ 15V  
from 5V supply. A pair of charge pump control circuits

NOTE: Intersil Pb-free products employ special Pb-free material sets;  
molding compounds/die attach materials and 100% matte tin plate  
termination finish, which are RoHS compliant and compatible with  
both SnPb and Pb-free soldering operations. Intersil Pb-free products  
are MSL classified at Pb-free peak reflow temperatures that meet or  
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
