General Description
The MIC2287 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 34V and a switch current of over 500mA, the MIC2287 easily drives a string of up to 8 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors.
