微源半导体 LP3382 SOT23-6 用于8PCS白色LED串联的高性能恒流开关稳压器
General description
The LP3382 is a 1MHz PWM boost switching regulator designed for constant- current white LED driver applications. The LP3382 can drive a string of up to 8 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3382 implements a constant frequency 1MHz 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 250 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.
