MIC2871
Description
The MIC2871 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 the use of very small inductor and output capacitor. These features make the MIC2871 an ideal solution for high-resolution camera phone LED flash light driver applications.
The MIC2871 operates in either flash or torch modes that can be controlled through the single-wire serial interface and/or external control pins. Default flash and torch brightness can be adjusted via an external resistor. A robust single-wire serial interface allows simple control by the host processor to support typical camera functions such as auto-focus, white balance, and image capture (flash mode).
The MIC2871 is available in a 14-pin 3mm × 2mm LDFN package with a junction temperature range of
- 40°C to +125°C.
