A new circuit was build and the familiar failure was observed. One fine day I went back to the shop where I satasheet purchase my LM and brought 2 additional LM for more testing. The following contains information that I learn from.

LMWT – Microchip – PCB Footprint & Symbol Download

Suitable for application that requires low noise. For exact component value design, you need to the datasheet. For more information on making your own PCB board, you may like to visit, website “.

The circuit was rebuild and it finally works.

The following guide uses typical resistor value. The output voltage of 5V cannot be sustain and eventually drop when more than 1A of current is draw by the load.

Click for MAX circuit. LMTO package. Long time ago, when technology is not so advance, resistor manufacturing is not unable to produce precise resistor value, as in today.

You need not have to understand formula to make your own inductor. Click for LMadj layout. 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.

LM Buck Converter equivalents, price and datasheet

A greenhorn when I first attempt to use inductor. Efficient pre-regulator for linear regulators. Adjustable version output voltage range. The LM, LMM series offers a high-efficiency replacement for popular three-terminal linear regulators. LM, LMM are available from several different. One Long screw, 2 board flat washer, 2 nut, 1 ring spacer, glue, and XXX is all the tools that is require to make your own air core inductor.

LM is actually quite difficult to find.

Low input voltage from 0. Written by Lim Siong Boon, last dated Dec Checking up on the previous IC, I notice that they are from the same manufacturing batch number and believe that they are already damage in some way. It also function as a multi-meter, and can be used to measure voltage, current, etc Please refer to MC for some handy information. One day, I visited a shop selling ready made inductors and brought LM at the same time.

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.

LM2576-5.0 Datasheet PDF

The mystery is resolve finally. TTL shutdown capability, low power standby mode. Suitable for battery powered circuit. WCR series- Surface mount resistors suitable for automatic placement.

LM2576-5.0 Buck Converter overview

The next thing that comes to mind, is the IC. The higher input voltage, the more heat is generated.

The capacitor used is suspected because the datasheet call for low ESR capacitor. Using a inductor meter to measure the inductance will be easier. Wide input voltage range, 40V.

However it is very big and bulky. MC slvab, Application Switching Regulator. Perheps the inductor used is not correct.
