ISL97651 Description
The ISL97651 integrates a high power, 4.4A boost converter for AVDD generation, an integrated VON charge pump, a VOFF charge pump driver, VON slicing circuitry and a buck regulator with 2A switch for logic generation. The ISL97651 have been designed for ease of layout and low BOM cost. Supply sequencing is integrated for both AVDD -> VOFF -> VON and AVDD/VOFF -> VON sequences.
