LP3322 Description
Features The LP3322 is a 1.1MHz PWM boost switching regulator designed for constant- current white LED driver applications. The LP3322 can drive a string of up to 10 white LEDs in series or 3s9p LEDs from 3.6V, ensuring uniform brightness and eliminating several ballast resistors. The LP3322 implements a constant frequency 1.1MHz PWM control scheme.
