Overview
Preliminary Datasheet LP3307 High Performance, Constant Current Switching Regulator For White LED General Description The LP3307 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 LP3307 implements a constant frequency 1MHz PWM control scheme.
Optimized operation frequency can meet ...
