MP3304B for LCD Backlight

Hello,

I would like to drive the MP3304A/B at 5V to control the back light for a 7" LCD screen from my microcontroller board. The backlight LEDs requires 9.6V and 540mA of current. I would also like to dim the backlight.

  1. May I please get a sample circuit for this purpose?
  2. Your datasheet doesn’t show how to select the inductor, its value, its maximum saturation current, nor the output capacitance. Can I please receive some instructions regarding this?
  3. My I also get detailed information regarding dimming the LEDs?
  4. Is there a better suited IC for my application?

Thank You
