MAX77387EVSYS中文资料Evaluation System for the MAX77387数据手册ADI规格书

描述 Description

The MAX77387 evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the highly integrated MAX77387 dual-phase adaptive step-up converter with 2A flash driver. The device’s flash driver integrates an adaptive 2A dual-phase PWM step-up DC-DC converter and two 1000mA white LED camera flash/movie high-side current regulators. The EV system includes the EV kit and a MINIQUSB command module that provides the I2C interface to control individual output on/off, the step-up output voltage, movie/ flash current, and flash/torch timer duration settings.
