ISL97642
FN6436.0
TFT-LCD DC/DC with Integrated
Amplifiers
The ISL97642 integrates a high performance boost regulator
with 2 LDO controllers for VON and VOFF, a VON-slice circuit
with adjustable delay and three amplifiers for VCOM and
VGAMMA applications.
The boost converter in the ISL97642 is a current mode PWM
type integrating an 18V N-Channel MOSFET.
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/μs slew rate. All inputs and outputs are
rail-to-rail.
Available in the 32 Ld thin QFN (5mmx5mm) Pb-free package,
the ISL97642 is specified for operation over the -40°C to +85°C
temperature range.

details on reel specifications.
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.
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
