Overview

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.

ISL8022EVAL1Z Buck Regulator Evaluation Board
ISL8022EVAL1Z Buck Regulator Evaluation Board
  • 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
