The ISL8033AEVAL1Z evaluation board is intended for use by individuals with requirements for point-of-load (POL) applications sourcing from 2.85V to 6V. The board is used to demonstrate the performance of the ISL8033A low quiescent current mode converter.


  • Dual 3A high-efficiency synchronous buck regulator with up to 95% efficiency
  • 180° out-of-phase
  • Power-good (PG) output with 1ms delay
  • 2.85V to 6V supply voltage
  • 2% output accuracy over temperature/load/line
  • Start-up with pre-biased output
  • Internal digital soft-start - 1.5ms
  • Soft-stop output discharge during disabled
  • External synchronization up to 6MHz typical 8µA 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



  • 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
