LP3302

Preliminary Datasheet LP3302 High Performance, Constant Current Switching Regulator For White LED General Description 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. 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.
