EL7584
4-Channel DC/DC Converter
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
V
ON
and V
OFF
supplies at 5V to 40V and 0V to -40V,
respectively, each at up to 60mA for V
BOOST
= 15V. The
V
COM
buffer provides up to 50mA continuous output current
from 2V to 13V.
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.
The EL7584 is available in a 24-pin TSSOP package and is
specified for operation over the full -40°C to +85°C
temperature range.
