The LMZ14203HEVAL/NOPB is an evaluation board for LMZ14203H, a simple switcher power module for high output voltage which can be easy to use DC to DC solution capable of driving up to a 3A load with exceptional power conversion efficiency, output voltage accuracy, line and load regulation. output voltage accuracy, line and load regulation. They are available in an innovative package that enhances thermal performance and allows for hand or machine soldering. The LMZ14203H evaluation board is configured for 12V output voltage from 15V to 42V input. The precision enable input allows for programmable UVLO of the input supply. The resistor voltage divider RENT and RENB set the input UVLO threshold. Connect the VIN turret terminal to the EN turret on the board to enable operation. The external soft start capacitor CSS facilitates controlled start up output rise time.
