MAX8834YEWP+T规格书详情
General Description
The MAX8834Y/MAX8834Z flash drivers integrate a 1.5A PWM DC-DC step-up converter and three programmable low-side, low-dropout LED current regulators. The step-up converter features an internal switching MOSFET and synchronous rectifier to improve efficiency and minimize external component count. An I2C interface provides flexible control of stepup converter output voltage setting, movie/flash mode selection, flash timer duration settings, and current regulator settings. The MAX8834Y/MAX8834Z operate down to 2.5V, making them future proof for new battery technologies.
