MIC2289 Détails du produit

General Description
The MIC2289 is a PWM (pulse width modulated), boost switching regulator that is optimized for constant-current white LED driver applications. The MIC2289 features an internal Schottky diode and three levels of output overvoltage protection providing a small size and efficient DC/DC solution that requires only four external components.

Features
• 2.5V to 10V input voltage
• Output voltage up to 34V
• Internal Schottky diode
• 15V, 24V, 34V output OVP options
• 1.2 MHz PWM operation
• Over 500mA switch current
• 95mV feedback voltage
• <1% line and load regulation
• <1µA shutdown current
• Overtemperature protection
• UVLO
• 2mm × 2mm 8-pin MLF® package
• –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
