Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very ...

This type of linear power supply has an extremely simple circuit consisting of a transformer, bridge rectifier, and capacitors. The transformer isolates and steps down the AC voltage, the ...

To make everything work, a load resistor on the 5V circuit makes the power supply think it’s hooked up to a motherboard. It’s all wrapped up in a neat slant-sided 3D-printed case that fits ...

Prefabricated isolated DC/DC converters and modules offer a simple but relatively expensive solution ... When a transformer is saturated, it appears as a short-circuit, which can damage other power ...

A simple resistor configuration yields ... This enables a variety of power (supply) profiles for digital logic circuits during power up as well as power down. Thus, the LTC2927 is suitable for ...

Due to less than perfect power-supply rejection ... The high-frequency performance of the simple ripple-eater is another advantage this circuit has over LDO regulation. Many LDOs, especially ...

Texas Instruments (TI) introduced four new SIMPLE SWITCHER nano power modules that redefine power supply design for space-constrained applications. The 17-V and 5-V modules feature high performance in ...
