Figure 1 shows the schematic diagram of the device. The design consists of two main parts: the main regulator circuit and the current-limiting circuit. IC3 is the LM338 5A positive linear regulator. 1 ...

Switched-mode power supplies are found in electronics all around us. They provide the DC voltages that power our computers, cell phones, chargers, appliances, and myriad other electronic devices.

Designing the correct power source is essential and complex, since there is no one typical application. While total automation of power supply design is yet to be achieved, a comprehensive range of ...

I have a couple of Chinese programmable lab power supplies. Both switch mode power supply (SMPS) systems are rated for 110V-220V AC input. But the UNI-T UTP1306 power supply has an input voltage ...
