    What Is the Difference Between a DC/DC Converter and a DC/DC Controller?

    Thanks Berkeman, yup, I guess you are right. Some of it having external circuit like protection circuit or filtering.

    What Is the Difference Between a DC/DC Converter and a DC/DC Controller?

    I am just wondering, what is the difference between a DC/DC converter or DC/DC Controller? It seems to be a same voltage converter IC?

    Transistor Base to Emitter Voltage

    Thanks Claude. See whether my interpretation of your explanation is correct: BJT in active region, VCE>VCE(sat): VBE(on) = nominal base emitter voltage. BJT in saturation region, VCE<VCE(sat), Ib>Ic/HFE BJT in active region, Ib higher, VBE(sat) higher. 1. What happens when VBE is lower...

    Transistor Base to Emitter Voltage

    I am sorry, you are right, I got the wrong value here. I am looking at this NPN transistor ZXTD6717E6, Diodes Inc. VCE(sat) = 0.245V max (havent seen such low VCEsat before) VBE(sat) = 0.93V typical VBE(on) = 0.865V typical If i am not wrong, When VCE > 0.245V and VBE > 0.93V the...

    Transistor Base to Emitter Voltage

    just wondering, what is the difference between Base-Emitter Saturation Voltage and Base-Emitter on Voltage ? VBE (sat) = 0.5V VBE (on) = 0.7V
