P1012AP13 Self-Supplied Monolithic Switcher

P1012AP13 Self-Supplied Monolithic Switcher

Pin No. (SOT−223) Pin No. (PDIP−7) Pin Name Function Description 1 1 VCC Powers the Internal Circuitry This pin is connected to an external capacitor of typic- ally 10 mF. The natural ripple superimposed on the VCC participates to the frequency jittering. For improved standby performance,.
