LP3390 - Constant Current Switching

LP3390 Description

Preliminary Datasheet LP3390 High Performance, Constant Current Switching for White LED and Boost Convertor General .
The LP3390 is a high frequency, asynchronous boost converter for constant current white LED driver applications.

LP3390 Features

* High Efficiency: 95%
* 1.2MHzFixed-Frequency PWM Operation
* Maximum Output Voltage up to 30V
* Operating Range : 2.5V to 5.5V
* Shutdown Supply Current:

LP3390 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 re
