When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable prices. Their ...

The key component of the dc power management system is the power supply that provides dc power for the associated system. The specific type of dc power management depends on its power input, which ...

Electronic equipment requiring dc power must adjust the ac input to a usable level with transformers or switching transistors and use a rectifier stage to convert the ac to dc. Primary ...

The digital low-dropout (LDO) linear regulator is one of the latest innovations in the power industry, bringing telemetry and adjustability to a linear power supply in a very small footprint. The ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

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 ...

Power supply manufacturers sometimes hear from customers with unfortunate dilemmas, such as, “I need to operate the power supply outside its rated voltage range.” Or, “What happens if I exceed my ...

We’ve often heard you should do everything twice. The first time is to learn what you need to do, and the second time is to do it right. We bet [Ian Carey] would agree after taking his old linear ...

Consumer electronics, industrial, robotics, medical, and military applications all frequently use an AC/DC power supply, also referred to as AC/DC converter. An accurate design of the power supply ...
