The MAX8630X evaluation kit (EV kit) is a fully assem-
bled and tested circuit for evaluating the MAX8630X
charge-pump white LED driver. The MAX8630X EV kit
operates from a 2.7V to 5.5V supply. Two pulse genera-
tor circuits are included on the board for evaluating the
serial-pulse dimming feature. The EV kit can also be
used to evaluate the MAX8630W with PWM dimming.
19-4272; Rev 0; 9/08
+ Denotes lead-free and RoHS compliant.
Note: Indicate that you are using the MAX8630X or MAX8630W when contacting these component suppliers.
