MIC2871YMK Product details

General 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.

Features
• Up to 1.2A flash LED driving current
• Highly-efficient, synchronous boost driver (up to 94%)
• ±5% LED current accuracy
• Control through single-wire serial interface or external control pins
• 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 14-pin 3mm × 2mm LDFN package

Applications
• Camera phones/mobile handsets
• Cell phones/smartphones
• LED light for image capture/auto focus/white balance
• Handset video light (torch light)
• Digital cameras
• Portable applications
