Product Details

The MAX20092 evaluation system is a matrix LED dimmer system featuring the MAX20092 12-switch matrix LED dimmer IC. The system includes two MAX20092 ICs that each control a string of 12 series LEDs. Each LED can be controlled individually or grouped. The user can turn the LED on and off with or without fading. The two strings of 12 series LEDs are driven by the MAX20097, a dual buck controller IC, with a current of 0.5A. The power supply for the dual buck controller is generated from the MAX16990, boost controller IC that is powered by an external 12V supply. For the detailed operation of the MAX20092 IC, refer to the MAX20092 IC data sheet.
