LED In Series General Description The LP3321 is a 1.0MHz PWM boost switching regulator designed for constant-current white LED driver applications. The LP3321 can drive a string of up to 11 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3321 implements a constant frequency 1.0MHz 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 200mV, which reduces the power dissipation in the current setting resistor. Highly integration and internal compensation network
