6 {6 b- `( f/ [5 hThe 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.
