There are many applications associated with MC34063, a few of them are Human Machine Interface (HMI), Portable devise, Measurement and test, Gas and blood analyzer, computing, Telecommunications, Cable solutions, etc. 1N5819

It works, BUT the output can be a bit spikey due to the high frequency switching nature of the device. However, it's very efficient because it uses stored energy (in an inductor and a capacitor) to convert the voltage. It has reasonable voltage regulation and output current limiting. It will survive a short circuit and protect the battery. Here is the 12v to 5v dc converter circuit for low current applications (< 70 mA), mainly for taking reference signal/ voltage and in a small current draining circuit like an LED indicator.Before getting to 12v to 5v converter circuit using different methods lets a glance at the need of 5 volt supply. In general, it should be noted that the cheaper the product the more likely it is to be of poor quality. You should consider your budget and stretch it as much as possible to get the best possible converter. Circuit 2 is a series Zener diode (or you could use a number of ordinary diodes in series to make up the voltage drop - say 12 x silicon diodes) Perhaps the most important element in your decision process is who made the converter and who is supplying it. In a perfect world, you will have heard of both the supplier and the manufacturer. You may even have personal experience with both of them. This will give you the confidence to buy their products. Here are some electrical properties of the 6 modules. I didn’t have module properties for “Cigar” so the ranges are based on chip specs and could be better than actual module ranges. Module

Over 80% of customers feel it is an excellent product. The main point to be aware of is that you’ll need a beefy charging cable to get the higher wattage rating needed for USB-C circuits. Make sure you select the right cable for your needs.Advanced Asynchronous Modulation (AAM) is a proprietary technology of MPS. With this technology in place, the IC will reduce its frequency when it detects low loads, thus reducing the overhead of switching but potentially introducing instability and ripples. A resistor’s value on the AAM pin determines when to start this behavior. Feel free to correct me in the comments if I am not explaining this correctly. Datasheets of some of the chips used in the modules contained an efficiency graph. The efficiency is a function of voltage and current. When available, I added the listed chip efficiency for the relevant Vin and Iout in the last column. Some modules have efficiency charts that don’t cover low current ranges, which might be an indication for the type of load the chips were (not) designed for. Output current of 25mA Module Higher switching frequency will mean less ripple on the output (more accurate voltage/current) but causes more overhead due to switching, which reduces the efficiency a bit. What makes “Fine” better than others? It is a relatively new IC. The datasheet is from 2014 where, for comparison, the MP2307’s is from 2008. It also features a very low Rds(on) values (90mΩ/40mΩ), but most interestingly the MP2315 has AAM (Advanced Asynchronous Modulation) power-save mode for light load.

There are many different reasons why you may need a 12V to 5V converter. If you are looking to reduce the supply and create a USB port then the Uctronics converter module could be the perfect solution for you.The above circuit diagram shows the circuit along with all the calculated values for our required operation. Working of 12V to 5V Circuit However, in the real world, this is not always the case. Instead of knowing the supplier and manufacturer, you need to discuss them with your family and friends. They may have personal experience that can be beneficial to you. It measures just 8.2cm by 5.1cm and has a light on top to tell you it is in use. It can handle –35V and still output a steady 5V supply. However, you should note it is not waterproof and the power supply is non-isolated. All the circuits have different performance. The voltage divider circuit is not recommended for use in the high current application as it has a low output current and lower efficiency. LM7805 12v to 5v converter:

Design a ‘Vout’ stabilized power supply to produce from an unregulated DC power supply source ‘Vs’. The maximum power rating P Z of the zener diode is in Watts. Using the zener diode and calculate using the following formulas: It works, BUT most of the power is dissipated by the Zener diode. Not very efficient! On the other hand it does give a degree of regulation if the load changes. However, if you short circuit the output, the magic blue smoke will break free from the Zener... Such a short circuit may also damage the 12V source once the Zener is destroyed.It has built-in overload protection, defends against short-circuits, and even protects against over-temperature. Best of all, you simply plug it in and start using it. Differences can be significant as seen above. At the lowest load test (25mA), the worst performer uses 3 times more power than the best. Of course, you may struggle to prove this is the case, leaving you without a device or a power supply converter.
