The MIC2873 is a high-current, high-efficiency flash LED driver. The LED driver current is generated by an integrated inductive boost converter with a 2MHz switching frequency which allows for the use of very small inductor and output capacitor. These features make the MIC2873 an ideal solution for high-resolution camera phone LED flash light driver applications. MIC2873 operates in either flash or torch modes 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 MIC2873 is available in a 9-bump 1.30mm x 1.30mm WLCSP package.
Additional Features
Up to 1.2A flash LED driving current
Highly efficient synchronous boost driver
Control through single-wire serial interface or external control pin
Input voltage range: 2.7V to 5.5V
True load disconnect
Configurable safety time-out protection
Output overvoltage protection (OVP)
LED short detection and protection
1μA shutdown current
Available in 9-bump 1.30mm x 1.30mm WLCSP package
