General Description
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 4 MHz switch-
ing frequency, which allows for the use of a very small
inductor and output capacitor. These features make the
MIC2874 an ideal solution for high-resolution camera
phone LED Flash light driver applications.
MIC2874 operates in either Flash or Torch mode that can
be controlled through the single-wire serial interface
and/or external control pin. A robust single-wire serial
interface allows the host processor to control the LED
current and brightness. The MIC2874 is available in a
9-bump 1.30 mm x 1.30 mm WLCSP package.
1.2A High-Brightness Flash LED Driver with
