LMZ21701 1A SIMPLE SWITCHER® Nano Module Evaluation Board


Order now


The LMZ21701 SIMPLE SWITCHER® nano module is an easy-to-use DC-DC solutions optimized for space constrained applications. The LMZ21701 EVM is capable of delivering 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 3.3V output voltage from 5V to 17V input. The resistor voltage divider RFBT and RFBB set the output voltage. The external capacitor CSS sets the softstart time for VOUT. See the datasheet for component selection and device details. The board features turret terminals for easy connection to input supply, load, EN input, as well as softstart voltage and power good flag monitoring.

  • Vin=5V to 17V
  • Vout=3.3V (default setting)
  • 1A max load
