LP3380 Datasheet (Lowpowersemi) - Constant Current Switching Regulator

LP3380, Constant Current Switching Regulator

The LP3380 is a 1MHz PWM boost switching regulator designed for constant-current white LED driver applications.

The LP3380 can drive a string of up to 8 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors.

The LP3380 implements a constant frequency 1MHz PWM co
