Typical Application for MIC2874: 1.2A High-Brightness Flash LED Driver with Single-Wire Serial Interface. The MIC2874 is a high-current, high-efficiency flash LED driver. The LED driver current is generated by an integrated inductive boost converter with a 4MHz switching frequency which allows for the use of very small inductor and output capacitor. These features make the MIC2874 an ideal solution for high-resolution camera phone LED flash light driver applications
