General Description
The MAX8631X evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX8631X white LED 1x/1.5x/2x charge pump with two LDOs. The MAX8631X EV kit drives 4 white LEDs for backlighting and uses 4 flash LED drivers to drive a flash LED module at a high current. The two 200mA LDOs are also available for evaluation. In addition to the LED driver circuit and LDOs, the EV kit includes one pulse-generator circuit and two momentary pushbutton switches that are used for testing the single-wire, serial-pulse-dimming and flash features of the MAX8631X. The MAX8631X EV kit can also evaluate the MAX8631Y. To evaluate the MAX8631Y, order a free sample along with this EV kit.
