STK740-441 : Number Pin name Description No.6106–3/10 STK740-441 Test Circuit 12 11 10 9 8 7 6 5 4 3 2 1 ON/OFF Vo adjust DC INPUT C1 FB L1 C2 OUTPUT (3.3V) GND C1 C2 L1 FB : 220µF/10V (OS capacitor) : 2200µF/6.3V : 30µH : Ferrite-bead core GND Overvoltage Protection Circuit In a constant-voltage power supply circuit output voltage may generally exceed the stipulated rating (equivalent to input voltage) when the circuit is broken down or the IC and the printed circuit board is wrongly soldered. Therefore overvoltage protection circuit is recommended to use to minimize the damages caused by the overvoltage. Sample the overvoltage protection circuit FUSE DC INPUT Regulator OUTPUT SCR GND.
STK740-470 : Number Pin name Description No.6107–3/10 STK740-470 Test Circuit 12 11 10 9 8 7 6 5 4 3 2 1 ON/OFF Vo adjust DC INPUT C1 FB L1 C2 OUTPUT (5V) GND C1 C2 L1 FB : 47µF/25V (OS capacitor) : 1000µF/16V×2 : 30µH : Ferrite-bead core GND Overvoltage Protection Circuit In a constant-voltage power supply circuit output voltage may generally exceed the stipulated rating (equivalent to input voltage) when the circuit is broken down or the IC and the printed circuit board is wrongly soldered. Therefore overvoltage protection circuit is recommended to use to minimize the damages caused by the overvoltage. Sample the overvoltage protection circuit FUSE DC INPUT Regulator OUTPUT SCR GND .
