ISL97645 Boost + VON Slice + VCOM RECOMMOEBNSDOEILSDLE9RT7EE6P4PL5RAAOCDEUMCETNT PART DATASHEET FN9263 Rev 1.00 December 14, 2007 OUT NEG POS AGND NC NC 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 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 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.
