ISL97652
4-Channel Integrated LCD Supply with
Dual V
COM
Amplifiers
The ISL97652 represents a high power, integrated LCD
supply IC targeted at large panel LCD displays. The
ISL97652 integrates a high power, boost converter for A
VDD
generation, delay switch, regulated V
ON
and V
OFF
charge
pumps, V
ON
slicing circuitry, a buck regulator for logic supply
generation and dual high power V
COM
amplifiers.
Operating at 650kHz or 1.3MHz, the A
VDD
boost converter
features a 2.8A boost FET. A short circuit protected A
VDD
delay switch is integrated to provide sequencing of the A
VDD
output. Feedback is taken from the far side of the delay FET
for improved regulation and an OVP circuit protects output
side components. The boost features programmable
soft-start.
The asynchronous buck converter features an integrated
2.5A FET. It also operates from the 650kHz or 1.3MHz
internal clock and features separate enable and soft-start
control.
The dual charge pump controllers used for V
ON
and V
OFF
generation uses the full F
OSC
switching frequency to allow
the use of small output components for board space
efficiency. V
ON
is further processed through an integrated
V
ON-SLICE
circuit for reduced flicker.
The integrated amplifiers feature high slew-rate and high
output current capability. They are permanently enabled
when AVIN is present.
Available in the 48 Ld 7mmx7mm QFN package, the
ISL97652 is specified for ambient 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.
