Product Details

The MAX16806 evaluation kit (EV kit) demonstrates the features of the MAX16806 high-current LED driver, capable of delivering regulated current of up to a total of 350mA to one or more strings of high-brightness LEDs with high accuracy. This EV kit operates at supply voltages between 5.5V to 40V and temperatures ranging from 0°C to +70°C.

The MAX16806 EV kit provides a user-selectable three-level LED current setting, connection to the 5V-regulated output, and a momentary switch to enable or disable the dimming function. This EV kit features wide-range dimming, controllable through a PWM input or analog input generated using an on-board trim pot. The MAX16806 EV kit is a fully assembled and tested PCB.

The MAX16806 EV kit provides access to the I²C interface of the MAX16806 IC, through which the internal dynamic registers and the EEPROM are written/read to control various device features. A CMAXQUSB board can be used to enable PC communication using the I²C 2-wire interface. Windows® 98SE/2000/XP-compatible GUI software is provided to access the MAX16806 IC. The MAX16806 EV kit can also be interfaced directly to a user-provided I²C system.

The MAX16806 evaluation system (EV system) consists of the MAX16806 EV kit and a companion CMAXQUSB serial-interface board. The CMAXQUSB interface board allows a PC to control an I²C interface using the USB port. Order the MAX16806EVCMAXQU+ for a complete PC-based evaluation of the MAX16806. Order the MAX16806EVKIT+ if you already have a CMAXQUSB interface board, or if you have your I²C interface, or do not require PC-based evaluation of the MAX16806.
