2.5A Regulator with Integrated High-Side MOSFET Evaluation Board


The ISL85403EVAL2Z board allows for quick evaluation of the ISL85403 synchronous buck or boost-buck controller in the non-inverting buck-boost configuration. It is a cost effective solution for the low-power, wide input voltage range point-of-load (POL) application where both stepping up and stepping down voltage capabilities are required.


  • Input voltage (VIN): 8V to 40V
  • Output voltage (VOUT): 12.0V
  • Max output current (IOUT_MAX): 1A
  • Switching frequency: 500kHz
  • Output ripple: 360mV at 1A load


  • General purpose
  • 24V bus power
  • Battery power
  • Point-of-load
  • Embedded processor and I/O supplies
