General Description
The MIC2287C is a 1.2MHz pulse width modulated (PWM), boost-switching regulator that is optimized for constant-current, white LED driver applications. With a maximum output voltage  of  37V  and  a  switch current  of  over  500mA,  the MIC2287C easily drives a string of up to 6 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors.

Features
•  2.5V to 10V input voltage
•  Output voltage up to 34V
•  Over 500mA switch current
•  1.2 MHz PWM operation
•  95mV feedback voltage
•  Output Overvoltage Protection (OVP)
•  Options for 15V, 24V, and 34V OVP
•  Over-temperature protection
•  UVLO
•  Low profile Thin SOT-23-5 package option
•  8-lead 2mm × 2mm MLF™ package option
•  –40°C to +105°C junction temperature range
•  For higher performance specifications see the MIC2287

Applications
•  White LED driver for backlighting:
  - Cell phones
 - PDAs
  - GPS systems
  - Digital cameras
  - MP3 players
  - IP phones
•  LED flashlights
