LP3380 Overview
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 control scheme.
