Preliminary Datasheet LP3384 High Performance, Constant Current Switching Regulator For 8PCS White LED In Series General Description he LP3384 is a 1MHz PWM boost switching regulator designed for constant- current white LED driver applications. The LP3384 can drive a string of up to 8 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3384 implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. To improve efficiency, the feedback voltage is set to 104 mV, which reduces the power dissipation in the current setting resistor. Highly integration and internal compensation network minimizes as 5 external component counts.
