+ T6 G8 o. N$ \- K- fThe 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.% `3 @: {+ T+ {7 _* p- S0 `0 \
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.
