LP3385 Datasheet (Lowpowersemi) - Constant Current Switching Regulator

LP3385, Constant Current Switching Regulator

The LP3385 is a 1.2MHz PWM boost switching regulator designed for constant- current white LED driver applications.

The LP3385 can drive a string of up to 10 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors.

The LP3385 implements a constant frequency 1.2MHz
