ISL97644

ISL97644 Boost + LDO + VON Slice + VCOM 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 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.
