    The MAX1576 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX1576 white LED 1x/1.5x/2x charge pump. This MAX1576 EV kit drives four white LEDs for backlighting and uses four flash LED drivers to drive one flash LED at a high current. In addition to the LED driver circuit, the EV kit includes one pulse-generator circuit and momentary pushbutton switches that are used for testing the single-wire serial pulse-dimming and flash feature of the MAX1576.
