LP3302 -1.1MHz PWM升压串联白光LED驱动


LP3302 General Description
The LP3302 is a 1.1MHz PWM boost switching regulator designed for constant- current white LED driver applications. The LP3302  can drive a string of up to 7 white LEDs from a 3.2V supply or 9 white LEDs from a 5V supply in series, ensuring uniform brightness and eliminating several ballast resistors.The LP3302 implements a constant frequency 1.1MHz 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.
