LED Driver General Description The LP3385 is a 1.2MHz PWM boost switching regulator designed for constant- current white LED driver applications. The LP3385 can drive a string of up to 10 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3385 implements a constant frequency 1.2MHz 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 300 mV, which reduces the power dissipation in the current setting resistor. Highly integration and internal compensation network m
