ISL97645A
FN6353.1
Boost + V_ON Slice + V_COM + Reset
The ISL97645A represents an integrated DC/DC regulator
for monitor and notebook applications with screen sizes up
to 20”. 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/µs slew rate, the
V_COM amplifier is capable of driving 400mA peaks, and
100mA continuous output current.

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details
on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-
free material sets, molding compounds/die attach materials, and
100% matte tin plate plus anneal (e3 termination finish, which is
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.
3. For Moisture Sensitivity Level (MSL), please see device
information page for ISL97645A. For more information on
MSL please see techbrief TB363.
