The ISL97645A represents an integrated DC/DC regulator
for monitor and notebook applications with screen sizes up
to 20鈥? The device integrates a boost converter for
generating A
VDD
, a V
ON
slice circuit, and a high performance
V
COM
amplifier.
The boost converter features a 2.6A FET and has user
programmable soft-start and compensation. With efficiencies
up to 92%, the A
VDD
is user selectable from 7V to 20V.
The V
ON
slice circuit can control gate voltages up to 30V.
High and low levels are programmable, as well as discharge
rate and timing.
The supply monitor can be used to monitor the input voltage
to prevent low voltage operation.
The integrated V
COM
features high speed and drive
capability. With 30MHz bandwidth and 50V/碌s slew rate, the
V
COM
amplifier is capable of driving 400mA peaks, and
100mA continuous output current.

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.
