Description
The MAX8685A evaluation kit (EV kit) is a fully assembled
and tested printed-circuit board (PCB) for evaluating
the MAX8685A xenon flash charger. The
MAX8685A EV kit operates from a 2.5V to 5.5V supply
and charges a 35µF capacitor to 300V. Battery voltages
as a low as 1.5V can be used to supply the inductor primary
current. The MAX8685A features an undervoltage
input monitor (UVI). UVI monitors the battery voltage
and suspends switching if the input voltage drops
below a programmed threshold. The MAX8685A also
features a voltage-monitor output that provides a
scaled replica of the output voltage. The current limit on
the MAX8685A EV kit is set to 2A (2.6A for the
MAX8685F), and is easily adjusted by adding a resistor.
An LED indicator on the EV kit lights up when the
initial charging cycle is complete.
