    Buck regulator with LM2596-adj got damaged.

    I build a circuit with LM2596HV-adj (smd IC). mounted it on a small heat sink. Input 37v dc input cap 100uf, output variable from 1.25v to 15v dc, output cap 220uf +330uf, inductor 100uh (toroidal). I used 2 flyback diodes (fast diode), one across output one between output pin and input pin of...

    Buck/Boost Converter

    Hello Everyone, I want to make a Buck/Boost converter having a range of 50V-450V of Input and Output of 230V. I want to ask that i have to use a dedicated IC or I should use a Microcontroller. Because I was going to make a Solar Inverter(1Kw,5Kw). I was going to use ESP 32 because it has many...

    8-100V to 5V-1A DC to DC Buck Converter using MP9486

    DC-to-DC buck converters are utilized ubiquitously in electronic devices. Three major types of non-isolated DC-to-DC converters are introduced: Buck, Boost, and Buck-Boost. The most frequently employed type is the Buck converter. In this article/video, I introduce a compact buck converter board...

    5A-35V Adjustable Switching Power Supply

    A DC-to-DC converter is one of the most commonly used circuits in electronics, especially in power supply applications. There are three major types of DC-to-DC converters (non-isolated): Buck, Boost, and Buck-Boost. Sometimes a buck converter is also called a step-down converter and a boost...

    I am a student and new to Power electronics,help me to figure out issue TIA.

    I have designed a 925v input to 24v output buck converter. I am facing a voltage drop to 0v and then it comes to back to 24v how can I get the straight line that is 24v without dropping of voltage in the circuit please anybody help me .

    Buck Converter Inductor choice for both heavy and light load

    Hi everyone, I have difficulty in selecting a proper inductor for a buck converter with TPS5430(Datasheet). The schematic I use is similar to the examples in the datasheet. After doing some research, I learned that a lower current load would prefer a higher inductance value whereas a higher...

    Driving a 0.8V peltier from 5V using PWM and H-Bridge

    Hello, I am wanting to control a small peltier module to regulate temperature in both hot and cold modes. I am thinking to use an H-bridge motor driver such as the MAX14870 so that I can feed a PWM signal from an Arduino, and another pin will select hot/cold using the DIR input. However, the...

    Buck converter not working as it should

    Hello everyone. I am doing a project in which I use a buck converter to convert high vtg to low vtg. Actually the input to the buck converter is from a solar panel which puts out 560 mA constant current and 34 V. And output is a 12V lead acid battery. The N- Channel mosfet is used at high side...
