LP3382 Datasheet (Lowpowersemi) - Constant Current Switching Regulator

LP3382, Constant Current Switching Regulator

The LP3382 is a 1MHz PWM boost switching regulator designed for constant- current white LED driver applications.

The LP3382 can drive a string of up to 8 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors.

The LP3382 implements a constant frequency 1MHz PWM c
