Switched Mode Power Supplies.

Module 2.3

Any positive voltage spikes greater than the maximum permitted input voltage around 35V or 40V or any negative spikes greater than Also take in to account the thermal resistance of the MOSFET juncion to case and any insulators between the case and the heat sink just add them all together.

You also get a rectifier and a case. CheapSlider Member May 24, Hero Banned May 780112, The other alternative is a switcher, Could you use an PSU from an old computer? If a circuit panel is unplugged whilst the supply is live it is possible that the ground connection to the I.

We do not charge a packaging or handling fee for this service, and you will receive an email when your order has been processed, you can collect half an hour after receipt of this email. The best way to do that is with surface area and fluid flow, thus the heat uc.


The IC can provide up to mA and is suitable for a wide range of input voltages. A large reservoir capacitor is not necessary, as the regulating action of the I. Recognise commonly used I. I can only suggest searching on 5V fixed voltage regulator and you should be able to find some options. You would take the positive supply from the amp kit and connect this to the input on the regulator, the ground would be the negative from the amp and also to the negative of the id.

Its cheaper to buy a battery charger than a 50 or 60W transformer. Mains hum is usually picked up if unshielded input wires are used. These charges are usually billed to you directly from UPS. Posted by Michael Lockhart on Thursday, 9 November Complementing the 78xx series is the 79 serieswhich offers I.

Hero Banned May 24, How well regulated does the output need to be? Regulated Power Supplies 3.

To participate you need to register. As such powering from a 9V supply you would be able to attach the regulator without an issue. Hero Banned May 28, I would looking at modifying an old 12V car battery charger – these usually give about 15 volts at around 4 to 6 amps which is ideal for making a 12v PSU.

12 Volt 1A Voltage Regulator 3-Pin TO – NTE

Hi Peter, You can run the amp kit from as little as 2V, however the higher the supply the better the quality. Most audio amplifiers reject mains hum that is from the power supply so that they don’t need a regulator.

7812 Regulator

Heromay be you can help me with this informationplease since you were the one who led me to the link. If you wanted to build a switching regulator you would have more of a chance, since they are 80 to 90 percent efficient.

Delivery times vary for international orders depending on the service selected and the destination. Short the input snd if the hum goes away then it is probably mains hum picked up by ix input wires. The maximum input voltage listed in table 1 shows that there is plenty of allowable difference between maximum and minimum input voltage, however it should be remembered that the higher the input voltage for a given output, the more power will need to be dissipated by the regulator.
