LP3311S Constant Current Switching Regulator

LP3311S Description

Preliminary Datasheet LP3311S High Performance, Constant Current Switching Regulator For 8PCS White LED In Series General .
The LP3311S is a 1MHz PWM boost switching regulator designed for constant current white LED driver applications.

LP3311S Features

* High Efficiency: 90% 
* 1MHz Fixed-Frequency PWM Operation
* Maximum Output Voltage up to 29V
* Operating Range : 2.7V to 5.5V
* Shutdown Supply Current:

LP3311S Applications

* The LP3311S can drive a string of up to 8 white LED in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3311S implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component size. To
