The MAX8717 EV kit provides dual 5V and 3.3V output voltages from the 6V to 24V battery input range. It delivers up to 5A output current for the 5V output and 5A for the 3.3V output with 95% efficiency. The EV kit operates at 300kHz switching frequency and has superior lineand load-transient response.
This EV kit is a fully assembled and tested circuit board. Both outputs are adjustable between 1.0V and 5.5V by changing feedback resistors R20, R21, R24, and R26.
