REMOEBNSDOELIDSELRT9EE86PP0LR2AOCDEUMCETNT PART 4-Channel Integrated LCD Supply with Dual V Amplifiers FN9287 Rev 1.00 November 2, 2007 The ISL97652 represents a high power, integrated LCD supply IC targeted at large panel LCD displays. The ISL97652 integrates a high power, boost converter for AVDD generation, delay switch, regulated VON and VOFF charge pumps, VON slicing circuitry, a buck regulator for logic supply generation and dual high power V amplifiers. Operating at 650k Hz or 1.3MHz, the AVDD boost converter Features a 2.8A boost FET. A short circuit protected AVDD delay switch is integrated to provide sequencing of the AVDD output. Feedback is taken from the far side of the delay FET for improved regulation and an OVP circuit protects output side ponents. The boost Features programmable soft-start. The asynchronous buck converter Features an integrated 2.5A FET. It also operates from the 650k Hz or 1.3MHz internal clock and Features separate...
