Overview

Description

The ISL8022EVAL1Z evaluation kit is intended for use by individuals with requirements for point-of-load (POL) applications sourcing from 2.8V to 5.5V. This evaluation board is used to demonstrate the performance of the ISL8022 low quiescent current mode converter.

Features

  • Dual 2A/1.7A high-efficiency synchronous buck regulator with up to 97% efficiency
  • 180° out-of-phase
  • Power-good (PG) output with 1ms delay
  • 2.8V to 5.5V supply voltage
  • 3% output accuracy over temperature/load/line
  • Start-up with pre-biased output
  • 40µA quiescent supply current in PFM mode
  • Selectable forced PWM mode and PFM mode
  • External synchronization up to 8MHz
  • Typical 6.5µA logic controlled shutdown current
  • 100% maximum duty cycle for lowest dropout
  • Internal current mode compensation
  • Peak current limiting, hiccup mode short circuit protection and over-temperature protection
  • Negative current detection and protection
  • Internal digital soft-start - 5ms
  • Soft-stop output discharge during disabled
