MIC2870
Description
The MIC2870 is a high-current, high-efficiency flash LED driver for one or two high-brightness camera flash LEDs.
The LED driver current is generated by an integrated inductive boost converter with 2MHz switching frequency which allows the use of a very-small inductor and output capacitor. These features make the MIC2870 an ideal solution for high-resolution camera phone LED flashlight driver applications.
MIC2870 supports two 750m A white-LEDs (WLEDs) or a single 1.5A WLED configuration. When two WLEDs are connected, their currents are matched automatically.
MIC2870 operates in either flash or torch modes that can be controlled through either an I2C interface or external pins. The brightness in the flash and torch mode can be adjusted via two external resistors individually. High-speed mode I2C interface provides a simple control at a clock speed up to 3.4MHz to support most camera functions such as auto-focus, white balance, and image capture (flash mode).
