PRELIMINARY
EL7640A, EL7641A, EL7642A
TFT-LCD DC/DC with Integrated
Amplifiers
The EL7640A, EL7641A, and EL7642A integrate a high
performance boost regulator with 2 LDO controllers for VON
and VOFF, a VON-slice circuit with adjustable delay and
either one (EL7640A), three (EL7641A), or five amplifiers
(EL7642A) for VCOM and VGAMMA applications.
The boost converter in the EL7640A, EL7641A, and
EL7642A is a current mode PWM type integrating an 18V
NHchannel MOSFET. Operating at 1.2MHz, this boost can
operate in either P-mode for superior transient response, or
in PI-mode for tighter output regulation.
Using external low-cost transistors, the LDO controllers
provide tight regulation for VON, VOFF, as well as providing
start-up sequence control and fault protection.
The amplifiers are ideal for VCOM and VGAMMA
applications, with 150mA peak output current drive, 12MHz
bandwidth, and 12V/
s slew rate. All inputs and outputs are
rail-to-rail.
Available in the 32 Ld thin QFN (5mm x 5mm) Pb-free
packages, the EL7640A, EL7641A, and EL7642A are specified
for operation over the -40°C to +85°C temperature range.

NOTE: Intersil Pb-free plus anneal 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.
