Features 3.0V to 60V Wide Input Voltage Integrated 250mQ60V Power MOSFET 1.2MHz Fixed Switching Frequency Up to 95%Step-up conversion efficiency 1mA Light load model efficiency up to 80% Low than 0.1mAstatic current Low than 10uAShutdown current Built-in Cycle-by-cycle current limiting Built-in thermal shutdown protection Built-in under-voltage protection Built-in loop compensation Built-in soft start circuit Simple external circuit 2.General Description The ZCC6303 is a constant frequencymode step-up converter intendedfor small,low power applications.TheZCC6303switches at 1.2MHz and allowsthe use of tiny, low cost capacitors andinductors 5mm or less in height. Internalsoft-start results in small inrush currentand extends battery life. ThezCC6303 includes under-voltagelockout,current limiting, and thermaoverload protection to prevent damage inthe event of an output overload. TheZCC6303 is available in a small 6-pinSOT-23or ESOP8 package. Available in a SOT-236 or ESOP8 package |
