描述 Description
The LP3311S is a 1MHz PWM boost switching regulator designed for constant current white LED driver applications. The LP3311S can drive a string of up to 8 white LED in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3311S implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component size. To improve efficiency, the feedback voltage is set to 200 mV, which reduces the power dissipation in the current setting resistor. Highly integration and internal compensation network minimizes as 5 external component counts. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency.
