ISL97646
FN6265.1
Boost + LDO + VON Slice + VCOM
The ISL97646 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, an integrated logic LDO 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 logic LDO includes a 350mA FET for driving the low
voltage needed by the external digital circuitry.
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 integrated VCOM features high speed and drive
capability. With 30MHz bandwidth and 50V/µs slew rate, the
VCOM amplifier is capable of driving 400mA peaks, and
100mA continuous output current.
