LMZ20501 1A SIMPLE SWITCHER® Nano Module Evaluation Board


Order now


The LMZ20501EVM is capable of driving up to 1A load with excellent power conversion efficiency, output voltage accuracy, line and load regulation and load transient response.  The evaluation board is configured for 1.8V output voltage from 2.375V to 5.5V input, based on the resistor voltage divider RFBT and RFBB.  The board has a double sided six pin connector and turret terminals for easy connection and input supply, ground and load.  The board features:  three pin jumpers for EN, mode and frequency response analyses, power good monitoring when connected to a rail , inductor current sensing using a wire loop across the multilayer vias before the output capacitors, jumper option for mode pin to run the part on PFM or PWM at light load, frequency response jumper to measure the response across injection voltage resistor and the enable jumper to measure the quiescent current of the module.

  • Vin = 2.7V to 5.5V
  • Vout = 1.8V
  • 1A max load
  • 3.0 x 6.5cm overall PCB size
