LP3310規(guī)格書詳情
描述 Description
The LP3310 is a 1.0MHz PWM boost switching regulator designed for constant-current white LED driver applications. The LP3310 can drive a string of up to 8 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3310 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 250mV, 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.
