Lowpowersemi LP3302
The LP3302 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 initially set with the external sense resistor.| Part No. | LP3302 |

GENERAL DESCRIPTION
To improve efficiency, the feedback voltage is set to 250mV, which reduces the power dissipation in the current setting resistor. The LP3302 implements a constant frequency 1MHz PWM control scheme. Optimized operation frequency can meet the requirement of small LC filters value .Highly integration and internal compensation network minimizes as 5 external component counts.to provide the best solution for PCB space saving and total BOM cost.
