The MAX8717 evaluation kit (EV kit) demonstrates the
MAX8717's standard application circuit. This dual-PWM
synchronous DC-DC converter steps down high-voltage
batteries and/or AC adapters, generating main
supplies for notebook computers.
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.
