Product Details

The MAX17105 evaluation system (EV system) consists of the MAX17105 evaluation kit (EV kit) and the Maxim CMAXQUSB+ command module. Windows® 2000/XP and Windows Vista®-compatible software is also available for use with the MAX17105EVCMAXQU+ EV system and can be downloaded from www.maximintegrated.com/evkitsoftware.

The MAX17105 EV kit is a fully assembled and tested surface-mount circuit board that evaluates the high-efficiency MAX17105 white LED (WLED) driver. The MAX17105 EV kit utilizes a step-up DC-DC converter to generate the voltage required to drive up to 8 strings of 12 surface-mount WLEDs. The EV kit uses a 7V to 24V input power and provides an adjustable 0mA to 30mA full-scale LED current. As shipped, the MAX17105 EV kit is configured to be evaluated with 4 strings of 10 WLEDs and includes an I²C/SMBus™-compatible interface that allows for software control of the brightness in 256 steps, backlight controller operating mode, manufacturer and silicon revision detection, and fault detection.

The Maxim CMAXQUSB+ command module provides the I²C/SMBus interface and is connected to the computer through the universal serial bus (USB) port. The MAX17105 EV kit software provides a graphical user interface (GUI) for exercising the MAX17105 features.
