Features  
General Description  
• TFT/LCD display supply  
- Boost regulator  
The EL7581C is a 3-channel DC:DC converter IC which is designed  
primarily for use in TFT/LCD applications. It features a 2.0V to 14V  
input capability and provides 5V to 18V output from a micropower  
boost converter. This output is designed to power the column drivers  
and can provide up to 600mA @15V, or 1A @5V output. A pair of  
charge pump control circuits provide regulated outputs of VON and  
- VON charge pump  
- VOFF charge pump  
• 2V to 15V VIN supply  
• 5V < VBOOST < 18V  
• 5V < VON < 40V  
VOFF supplies at 8V to 40V and -5V to -40V, respectively (depending  
on the VBOOST set and external component configuration), each at up  
to 15mA.  
• -40V < VOFF < 0V  
• VBOOST = 5V @1A  
The EL7581C features adjustable switching frequency, adjustable soft  
start, and each supply channel has a separate output enable control to  
allow selection of supply start-up sequence. An over-temperature fea-  
ture is provided to allow the IC to be automatically protected from  
excessive power dissipation.  
• VBOOST = 12V @700mA  
• VBOOST = 15V @600mA  
• High frequency, small inductor  
DC:DC boost circuit  
• Over 90% efficient DC:DC boost  
converter capability  
• Adjustable frequency  
• Adjustable soft-start  
• Adjustable outputs  
• Small parts count  
The EL7581C is available in a 20-pin HTSSOP package and is speci-  
fied for operation over the full -40°C to +85°C temperature range.
