300kHz Dual, 180° Out-of-Phase, Step-Down PWM Controller Evaluation Boards


The ISL6440EVAL1Z evaluation board highlights the operation of the IC in an embedded DC/DC converter application. The ISL6440 is a high performance triple-output controller offering control and protection features for 2 synchronous buck PWMs. 

Key Features

  • Wide Input Supply Voltage Range: 5.6V to 24V, 4.5V to 5.6V
  • Two Independently Programmable Output Voltages
  • Switching Frequency 300kHz
  • Out of Phase PWM Controller Operation: Reduces Required Input Capacitance and Power Supply Induced Loads
  • No External Current Sense Resistor: Uses Lower MOSFET's rDS(ON)
  • Programmable Soft-Start
  • Extensive Circuit Protection Functions:PGOOD, UVLO, Overcurrent, Overtemperature, Independent Shutdown for Both PWMs
  • Excellent Dynamic Response: Voltage Feed-Forward with Current Mode Control


  • Power Supplies with Two Outputs
  • xDSL Modems/Routers
  • DSP, ASIC, and FPGA Power Supplies
  • Set-Top Boxes
  • Dual Output Supplies for DSP, Memory, Logic, µP Core and I/O
  • Telecom Systems
