Evaluation Kit for the MAX8834Y/MAX8834Z (MAX8834YEVKIT) (MAX8834YEVKIT)

The MAX8834Y evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the highly integrated MAX8834Y adaptive step-up converter with 1.5A flash driver. The MAX8834Y flash driver integrates an adaptive 1.5A PWM step-up DC-DC converter, two 750mA white LED camera flash/movie current regulators, and a 16mA indicator LED current regulator. The EV kit includes a MAXQ2000 microcontroller command module that provides the I²C interface to control individual output on/off, the step-up output voltage, movie/flash current, and flash timer duration settings.

The MAX8834Y evaluation software can be downloaded from www.maximintegrated.com/evkitsoftware. The MAX8834Y EV kit can also evaluate the MAX8834Z. To evaluate the MAX8834Z, order a free sample along with the MAX8834Y EV kit.
