Overview

DATASHEET ISL8022 Dual 2A/1.7A Low Quiescent Current 2.25MHz High Efficiency Synchronous Buck Regulator FN7650 Rev 3.00 March 14, 2013 The ISL8022 is a high efficiency, dual synchronous step-down DC/DC regulator that can deliver up to 2A/1.7A continuous output current per channel.

The channels are 180° out-ofphase for input RMS current and EMI reduction.

The supply voltage range of 2.8V to 5.5V allows for the use of a single Li+ cell, three NiMH cells or a regulated 5V input.

Key Features

  • include internal digital soft-start, enable for power sequence, overcurrent protection, and thermal shutdown. The ISL8022 is offered in a 4mmx3mm 12 Ld DFN package with 1mm maximum height. The complete converter occupies less than 1.8cm2 area. Features.
  • Dual 2A/1.7A high efficiency synchronous buck regulator with up to 97% efficiency, low iq (40µA).
  • 180° out-of-phase.
  • Start-up with pre-biased output.
  • Selectable forced PWM mode and PFM mode.
  • External.
