Automotive Dual Synchronous Buck Controller with Integrated Drivers Evaluation Board


The ISL78264EVAL1Z evaluation board is used to evaluate the two-channel synchronous buck converter operation of the ISL78264 dual buck controller in which the converters have a 180° phase shift to minimize input capacitor stress. The board demonstrates the high efficiency of synchronous buck operation and all the features of the ISL78264 IC including overcurrent protection, overvoltage and undervoltage protection, and power-good indication for each channel.

Key Features

  • VIN operating range: 3.75V to 42V
  • Selectable forced PWM or ECM mode with Iq = 6μA (on channel)
  • Programmable switching frequency (200kHz to 2.2MHz)
  • Dropout mode for high duty-cycle operation
  • 20ns on-times for low duty-cycle operation
  • External synchronization
  • Programmable spread spectrum clocking
  • 180° phase shift between channels
  • 2A sourcing/3A sinking MOSFET drivers
  • Boot UVLO and programmable boot refresh time
  • Comprehensive fault protections for OV/UV/OC/OT
  • Monitor test points for key signals


  • Automotive 12V systems
  • Infotainment/Multimedia systems
  • Cockpit safety systems
  • Advanced Driver Assist Systems (ADAS)
