1 / 13 page  Preliminary Datasheet LP3302 LP3302B6F-00 Version 1.0 Datasheet May.-2013 www.lowpowersemi.com Page 1 of 13 High Performance, Constant Current Switching Regulator For White LED 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 8 white LEDs from a 3.2V supply or 21 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 size. 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. Ordering Information LP3302 F:Pb-free Package Type B6：SOT23-6 Features High Efficiency: 88% 1.1MHz Fixed-Frequency PWM Operation Maximum Output Voltage up to 29V Operating Range : 2.7V to 6V Shutdown Supply Current:<1uA Available in SOT23-6 Package Built-in Over Voltage Protection Minimize the External Component RoHS Compliant and 100% Lead Pb-Free Pin Configurations Applications WLED Backlight driver OLED Backlight driver PDA DSC Camera Flash WLED driver |
