Preliminary Datasheet LP3321 High Performance, Constant Current Switching Regulator For 10PCS White LED In Series General Description The LP3321 is a 1.3MHz PWM boost switching regulator designed for constant- current white LED driver applications. The LP3321 can drive a string of up to 10 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3321 implements a constant frequency 1.3MHz PWM control scheme. The high frequency PWM operation also saves.
