MIC2287C Micrel MIC2287C 1.2MHz PWM White LED Driver with OVP in 2mm × 2mm MLF™ and Thin SOT-23 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. The MIC2287C implements a constant frequency, 1.2MHz PWM control scheme. The high frequency PWM operation saves board space by reducing external component sizes.
