Data Sheet
December 14, 2007
FN9228.1
Boost + LDO + V ON Slice + V COM
The ISL97644 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, an integrated logic LDO 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 logic LDO includes a 350mA FET for driving the low
voltage needed by the external digital circuitry.
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 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.
