Applications/Uses

Description

The MAX8645Y evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX8645Y white LED 1x/1.5x/2x charge pump with two LDOs. This MAX8645Y EV kit drives 6 white LEDs for backlighting and uses 2 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 MAX8645Y. The MAX8645Y EV kit can also evaluate the MAX8645X. To evaluate the MAX8645X, order a free sample along with this EV kit.
