4-Channel DC/DC Converter  
Features  
• TFT-LCD display supply  
- Boost regulator  
The EL7584 is a 4-channel DC/DC converter IC which is  
designed primarily for use in TFT-LCD applications. The  
boost converter has 2V to 14V input capability and provides  
5V to 17V output, which powers the column drivers and  
provides up to 370mA @ 15V. A pair of charge pump control  
circuits provide outputs to allow the external generation of

The EL7584 features adjustable switching frequency and on-  
chip power sequence to simplify start-up operation. A  
separate input is available to externally increase the default  
delay of the positive charge pump. An over-temperature  
feature is provided to allow the IC to be automatically  
protected from excessive power dissipation.

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.  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
