MIC2870 - 1.5A Synchronous Boost Flash LED Driver

General 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.

Key Features

  • make the MIC2870 an ideal solution for high-resolution camera phone LED flashlight driver.

MIC2870 1.5A Synchronous Boost Flash LED Driver with I2C Interface General 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 750mA 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.
