Adjustable dual-level constant-current load reference design for transient testing


Design files


This adjustable dual-level constant-current load reference design helps engineers test a power supply output load transient response with special features and easy operation. The board provides load transient adjustments for low and high level with slew rates as high as 100 A/µs. Timing adjustments such as period, delay and pulse width are also designed into the board.

  • Easily-adjustable load transient parameters
  • Slew rates as high as 100 A/µs
  • Settling time adjustment to minimize overshoot and oscillations
  • 9-V battery input with low battery alert
  • Temperature monitoring and shutdown
