MIC2870 Datasheet (Micrel Semiconductor) - 1.5A Synchronous Boost Flash LED Driver

MIC2870, 1.5A Synchronous Boost Flash LED Driver

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.

MIC2870 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
