ZCC6303 60V宽电压输入升压芯片，恒流驱动LED芯片 兼容SY7200

ZCC6303  3.0V~60V宽电压输入升压芯片，恒流驱动LED芯片General Description   The ZCC6303 is a constant frequency ,mode step-up converter intended forsmall ,low power applications .The ZCC6303 switches at 1.2MHz and allows theuse of tiny ,low cost capacitors and inductors 5mm or less in height. Internalsoft-start results in small inrush current and extends battery life.   The ZCC6303 includes under-voltage lockout ,current limiting ,and thermaloverload protection to prevent damage in the event of an output overload .TheZCC6303 is available in a small 6-pin SOT-23 package.Features ·3.0V to 60V WideInput Voltage ·Integrated 250mΩ 60V Power MOSFET ·1.2MHz FixedSwitching Frequency ·U to 95% Step-upconversion efficiency ·1mA Light load modelefficiency uo to 80% ·Low than 10uAShutdown current ·Low than 0.1mA staticcurrent ·Built-inCycle-by-cycle current limiting ·Built-in thermalshutdown protection·Built-in under-voltage protection·Built-in loop compensation·Built-in soft start circuit·Simple external·Available in a 6-pin SOT-23 packageApplications·DigtialSet-top Box(STB)·TabletPersonal Computer(Pad)·LCD Bias Supply·Battery-PoweredEquipment·Portable MediaPlayer(PMP)·GeneralPurposes
