概要

The ISL8088EVAL1Z evaluation board is intended for use by individuals with requirements for point-of-load (POL) applications sourcing from 2.75V to 5.5V. This evaluation board is used to demonstrate the performance of the ISL8088 low quiescent current mode converter.

  • Dual 800mA high-efficiency synchronous buck regulator with up to 97% efficiency
  • 800mA guaranteed output current per channel
  • Power-good (PG) output with 1ms delay
  • 2.75V to 5.5V supply voltage
  • 3% output accuracy over temperature/load/line
  • Start-up with pre-biased output
  • Internal digital soft-start - 2ms
  • Soft-stop output discharge during disabled
  • 30µA quiescent supply current in PFM mode
  • Selectable forced PWM mode and PFM mode
  • External synchronization up to 4MHz
  • Typical 6.5µA logic controlled shutdown current
  • 100% maximum duty cycle for lowest dropout
  • Internal current mode compensation
  • Peak current limiting
  • Over-temperature protection
  • Independent enable
  • DC/DC POL modules
  • µC/µP, FPGA and DSP power
  • Plug-in DC/DC modules for routers and switchers
  • Test and measurement systems
  • Li-ion battery power devices
  • Barcode readers
