LPS Microsource Semiconductor LP3321B6F voltage regulator. The LP3321 is a 10MHz PWM step-up switching regulator designed for constant current white LED driver applications. The LP3321 can drive up to 11 strings of white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3321 achieves a constant frequency of 10MHz PWM control scheme. High-frequency PWM operation also saves board space by reducing the size of external components. To improve efficiency, the feedback voltage is set to 200mV, which reduces the power dissipation in the current setting resistor.
