Design calculator might not work on some web browser. The photos on the left column shows the LM circuit using the correct inductance value at uH but the inductor is low power rated. Some of the various sizes of inductor tested and seems to be working with LM Low input voltage from 0. Failure, ,m2576-5.0 first prototype circuit to test out the performance of LM, LM It is advisable to supply a voltage input range from 7.

Try sourcing your local electronics shop for one if possible.

Wide input voltage 6Vdc to 42Vdc. Quite weird actually, and I couldn’t figure it out the actual problem I had in my previous attempt. A greenhorn when I first attempt to use inductor.


If the amount current continue to flow through the inductor, the inductor is basically becoming a heater. One using a wire coil inductor, and the other smaller one inductor that looks like a resistor with it’s color bands. Simply input the inductance value you need, the program will display a table containing the wire coil height radius and number of turns required. Inductance value can be observe immediately for lm2576-50 modification to the coil of wire. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator.

Circuit diagram taken from. Requiring a minimum number of external components.

Home fabricated circuit board. Schottky diode Schottky Barrier Rectifiermeans that the forward voltage drop is low. It is either coil one myself or buy one from shop.

It is really interesting. Just that making your own inductor takes up time and it is very likely to cost you more than what a shop might be selling. When I started writing this acticle, only did I realize that I have actually tried it about 6 months ago.

However it is very big and bulky. If you are interested in making your own coil, you might interested in this website, http: Adjustable version output voltage range. To find the range of resistor value that is available in the lm2576-55.0, multiply the normalise standard found in the table in terms of A standard series of inductors optimized for use with lm257-65.0 LM, LMM are available from several different manufacturers.

For -negative voltage supply, you can use LM79xx series. The transistor forms the oscillating circuit generating pulsing output.

Realizing that this circuit drive high current load, I should use a thicker inductor coil. This means that I can keep fewer resistance range and easily stock larger quantity for each value. The experiment compare between the performance of using different satasheet.

After further testing, I find out that ordinary capacitor works as well. Using various type of inductor and capacitor.

Low input voltage from 1.
