The ISL97645 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 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.
