    0-30 Vdc Stabilized Power Supply

    Capricious, The 13.8V psu have less voltage difference between the rectifier and the output than this variable one. To calculate the power burning off to heat (rectifier Voltage

    Switching power supply

    vainajala, Yes you have to arrange the supply and the TTL level for the input to use these drivers. The IRF9540N is a P-channel and it will work whit the MAX627. There are other MOSFET drivers out there just search for

    i need a datasheet for GD 74LS174......

    Fatoota, http://engineering.dartmouth.edu/~engs031/databook/sn74ls174.pdf http://www.learn-c.com/74ls244.pdf http://www.fairchildsemi.com/ds/LM/LM7805.pdf But the last one I don't know, how does it look, what kind of capsule is it? Ante ::)

    0-30 Vdc Stabilized Power Supply

    Capricious, The 200 deg.C apply inside (junction) not the surface of the capsule, when it reaches 200 deg.C outside it

    darlington optocoupler

    ginji, If it is external and for protection of your computer you can use almost any opto with the right voltage. Ante ::)

    Switching power supply

    Vainajala, To get a better efficiency try to use a MOSFET driver as I suggested earlier the MAX 626/627 or similar. This circuit will assure that the MOSFET:s switches on and of properly. Ante ::)

    darlington optocoupler

    Ginji, Are you sure it is broken? This is a component that does not break down under normal conditions. Ante

    Switching power supply

    audioguru, I still think the Darlington is the better choice. We are talking about pulses that are of different length (PWM) and between the pulses the transistor

    Switching power supply

    audioguru vainajala, The collector outputs in the 494 can sink 200mA maximum, will this suffice as base current for three transistors? What makes you think that a Darlington can

    Switching power supply

    vainajala, Try to use a 2.2k for R3. As far as I can see the emitters and collectors of the TL 494 is correctly connected. With the change of R3 the efficiency should improve a bit and the heat in R2 will be reduced. Have you access to a scope? I would be useful to see how Q1 performs and...
