The MAX8622 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX8622 Xenon flash charger. The MAX8622 EV kit operates from a 2.5V to 5.5V supply, and charges a 150µF capacitor to 300V. Battery voltages as low as 1.5V can be used to supply the inductor primary current. The current limit on the EV kit is set to the default of 1.6A, but is easily adjusted by adding a resistor. An LED indicator on the EV kit lights up when the charging cycle is complete.
