MIC3287 Product details

General Description
The MIC3287 is a 1.2MHz pulse width modulated (PWM) step-up switching regulator that is optimized for constant current white LED driving applications. With a switch current of over 350mA, the MIC3287-24 drives a string of up to 4 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors.

Features
• 2.8V to 6.5V Input Voltage
• 350mA Switch Current
• 1.2 MHz PWM Operation
• 250mV Feedback Voltage
• Optional 24V Output Over-Voltage Protection (OVP)
• Up to 36V Output Voltage without OVP
• <1% Line and Load Regulation
• <1µA Shutdown Current
• Over-Temperature Protection
• Under-Voltage Lock Out (UVLO)
• Low Profile Thin SOT-23-5 Package Option
• Low Profile Thin SOT-23-6 Package Option
• 8-pin 2mm x 2mm MLF® Package Option
• –40°C to +125°C Junction Temperature Range

Applications
• White LED Driver for Backlighting:
    - Cell phones
    - PDAs
    - GPS systems
    - Digital cameras
    - MP3 players
    - IP phones
• LED Flashlights
• Constant Current Power Supplies
