MAX8834YEVKIT：Evaluation Kit for the MAX8834Y/MAX8834Z
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.
