STK3041A Price
VIN (Pin 2): This is the collector ofthe on-chip power NPN switch. This pin powers the internal circuitry and internal regulator. At NPN switch on and off, high dl/dtedges occur through this pin. Keepthe external bypass and catch diode close to this pin. Trace inductance in this path will create a voltage spike at switch off, adding to the VCE voltage across the internal NPN.
