Synchronous Buck Converter Evaluation Boards


The ISL8115EVAL1Z and ISL8115EVAL2Z are synchronous buck converter evaluation boards that are used to implement Renesas' ISL8115 wide input range pulse width modulation (PWM) controller. Utilizing voltage mode control with input feed-forward, these boards maintain a constant loop gain for optimal transient response, especially for applications with a wide input voltage range.

Key Features

  • Wide VIN range operation: 2.97V to 36V; up to 5.5V output and 30A load current per phase
  • Fast transient response
    • Voltage-mode PWM leading-edge modulation with non-linear control
    • Input voltage feed-forward
  • Integrated 5V high-speed 4A MOSFET gate drivers
    • Internal bootstrap diode
  • Oscillator programmable from 150kHz to 1.5MHz
    • Frequency synchronization to external clock signal
  • Diode emulation mode for light load efficiency improvement
  • Output OVP/UVP, OCP and OTP
  • Power-good (PGOOD) open drain output
  • Adjustable soft-start
  • Pre-bias start-up function
  • Excellent output voltage regulation
    • 0.6V ±1.0% internal reference (-40 °C ~ 125 °C)
    • 0.6V ±0.7% internal reference (-40 °C ~ 105 °C)
    • Differential voltage sensing


  • Power supply for datacom/telecom and point-of-load (POL)
  • Wide input voltage range buck regulators
  • High current density power supplies RF power amplifier bias compensation
