LP3390 Datasheet (Lowpowersemi) - Constant Current Switching

LP3390, Constant Current Switching

The LP3390 is a high frequency, asynchronous boost converter for constant current white LED driver applications.

The internal MOSFET can support up to 8 White LEDs for backlighting and OLED power application,and the internal soft start function can reduce the inrush current.

The LED current is initi
