1 Introduction

The LMZ21701 and LMZ21700 SIMPLE SWITCHER® nano modules are easy-to-use DC-DC solutions optimized for space constrained applications. The LMZ21701 is capable of driving up to 1-A load with excellent power conversion efficiency, output voltage accuracy, line and load regulation, and load transient response. The LMZ21700 is a 650-mA load current version module, pin-to-pin compatible with the LMZ21701. The evaluation board is configured for 3.3-V output voltage from 5-V to 17-V input. The resistor voltage dividers, R_FBT and R_FBB, set the output voltage. The external capacitor C_SS sets the soft-start time for V_OUT. See the LMZ21701 1-A Nano Module With 17-V Maximum Input Voltage or LMZ21700 650-mA Nano Module With 17-V Maximum Input Voltage data sheets for component selection and device details. The board features turret terminals for easy connection to input supply, load, EN input, as well as soft start voltage and power-good flag monitoring.
