October 21, 2010 Boost + VON Slice + VCOM + 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 AVDD, a VON slice circuit, and a high performance
VCOM amplifier.
The boost converter features a 2.6A FET and has user
programmable soft-start and compensation. With efficiencies
up to 92%, the AVDD is user selectable from 7V to 20V.
The VON 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. Features 2.7V to 5.5V Input 2.6A Integrated Boost for Up to 20V AVDD Integrated VON Slice RESET signal generated by Supply Monitor 600kHz/1.2MHz fS VCOM Amplifier
