MIC2871
Overview
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.
- 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
