ISL97652 - 4-Channel Integrated LCD Supply

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 components. The boost features programmable soft-start. The asynchronous buck converter features an integrated 2.5A FET. It also operates from the 650kHz or 1.3MHz internal clock and features separate en.
