    heat sink for transfomer

    yes another transformer heat is only 5-10% of the heat of the the first one but the faulty transformer was still working and giving good voltage even it is short it is possbile.

    how to design very small 6V power supply @100mA

    i have open one of the charger i found no ic in it but just a small transformer and 1 or  2 transistor. and other components. thats it. i donot know how much ripple is there in the ouput of charger as i don't own cro.

    heat sink for transfomer

    i think this is the problem so how to check the transfomer quality in my city the quality is poor most of the times is there any method to check transformer quality I  tested my ckt without load and even without regulator ckt only transformer was kept on and i observed that 70-80% percentange...

    heat sink for transfomer

    my ckt required only 200mA at 5.1V and transformer rating says 9Vac 500mA

    heat sink for transfomer

    how to reduce transformer heating how to take away heat from the transfomer as we use heatsing for transistors is this possible with transformer My ckt needs 5.1V@200mA i have used 9Vac transformer 500mA rating on its box i cann't say how much it can deliver. Now i am drawing only 200mA even...

    Serial communincation between two Microcontroller using IR

    i have done that in very good manner using TSOP1738 as reciever and a IR led driven by NE555 as transmitter. now to send signals you just have to connect the reset pin of NE555 to Tx of 89c51 and that it and write a simple test program. now TSOP1738 is costlier then simple ir-photodiode but...

    how to design very small 6V power supply @100mA

    Guru Can you provide me some guidance for designing such a supply even some good links can help me...........Smallest possibe............ zak4000  can know what are these from http://en.wikipedia.org/wiki/Switching_power_supply

    how to design very small 6V power supply @100mA

    i have little idea that this can be done by two methods 1> Tansformerless design 2> Switching power supply design now i want to have very small transformer or no transformer at all
