Microchip Technology MIC2870
The MIC2870 is a high-current, high-efficiency flash LED driver for one or two high-brightness camera flash LEDs. The LED drive current is generated by an integrated inductive boost converter with 2 MHz 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.| Part No. | MIC2870 |

GENERAL DESCRIPTION
MIC2870 supports two 750 mA 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 mode 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.
