LM2576-5.0WU Data Sheet – Microchip Technology

This brings me the idea of forming the required resistance from two commonly stocked resistor connecting in parallel.

The lab power supply display a current loading limit warning.

WH series- Aluminium clad resistors for applications where high power dissipation in a small space is required. The capacitor used is suspected because the datasheet call for low ESR capacitor. For more information on making your own PCB board, you may lm25766-5.0 to visit, website “. A switching mode power supply such as LM dc-dc converter, uses switching control to reduce the input dc voltage on average.

Realizing that this circuit drive high current load, I should use a thicker inductor coil. It is so fortunate that I managed to get this circuit working once again.

The standard EIA decade resistor value is group into different series. Never able to find out the inductance value I have. The following guide uses typical resistor value. The circuit using a high power rating inductor on the right shows a cleaner DC supply, although the inductance value is different from the design. The transistor forms the oscillating circuit generating pulsing output.

All inductor works too, big or small. The rest of the cells present the various possible resistance I can obtain by having the resistance in parallel from the respective row and column.

The 1N is a high current, high speed, schottky diode and is suitable for this digital switching circuit. Diode references from Diotec.

Still it doesn’t work. One day, I visited a shop selling ready made inductors and brought LM at the same time. If you want the output voltage adjustable, there is also a adj model. Fortunately, there is this inductance measurement product selling at an affordable price.

LM is actually quite difficult to find. However it is very dtaasheet and bulky. It is rated at output 5Vdc 16A and generate far less heat. It has been some time since I learn adtasheet use LM Simply input the inductance value you need, the program will display a table containing the wire coil height datazheet and number of turns required.

So I purchase the IC and its component to try it out. Low input voltage from 1Vdc to output voltage up to 3. Input voltage needs to be at least 7V up to a maximum of 20V in order for LM to regulate at an output of 5V. LM seems very common from shops around and I decided to find out more about this lm5276-5.0.

It has been tested to support a RF transceiver operating at 5V without any issue observed. According to the document, it is ok for the inductance to be higher.

The following table provides a quick reference for power supply circuit. Too bad, I do not have the right inductor to experiment further. Nowadays dc-dc converter are getting smaller and comes in the TO package too. The following experiment is done during the 1st test on LM circuit. They are usually one of the important specification to take note while selecting inductor from datasheet.
