MAX1714A Evaluation Kit  
General Description  
Features  
The MAX1714A evaluation kit (EV kit) demonstrates  
a standard 4A application circuit. This DC-DC con-  
verter steps down high-voltage batteries and/or  
AC adapters, generating a precision, low-voltage  
rail for use as chipset, DRAM, and other low-voltage  
supplies. For higher current applications up to 12A,  
refer to the MAX1714A data sheet.

BATT  
The MAX1714A EV kit provides a 2.5V output voltage  
from a +5V to +24V battery input range. It delivers up to  
4A output current with greater than 90% efficiency while  
operating at a 300kHz switching frequency, and has  
superior line- and load-transient response.

Power-Good Output  
This EV kit is a fully assembled and tested circuit  
board. It also allows evaluation of other output voltages  
in the 1.0V to 5.5V range by changing feedback resis-  
tors R1 and R2.
