ISL97645
FN9263.1
Boost + V_ON Slice + V_COM
The ISL97645 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 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.
