LP3390規(guī)格書(shū)詳情
描述 Description
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 initially set with the external sense resistor. To improve efficiency, the feedback voltage is set to 200mV, which reduces the power dissipation in the current setting resistor. The LP3390 implements a constant frequency 1.2MHz PWM control scheme. Optimized operation frequency can meet the requirement of small LC filters value .Highly integration and internal compensation network minimizes as component counts.to provide the best solution for PCB space saving and total BOM cost. DFN-10 3*3mm packages.
