- Typical Application for MIC3287: 1.2MHz PWM White LED Driver with OVP in 2mm x 2mm MLF and Thin SOT-23. 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 maximum output voltage of 24V and a switch current of over 350mA, the MIC3287 drives a string of up to four white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors
