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 pr… ...

You can add this sequencing circuit to any power-supply controller that provides access to its reference voltage, soft-start capacitors, and output-voltage resistor-divider network. Figure 2 The 2.5 ...

There are many existing design examples, including Linear Technology demo boards and data sheet circuits in the LTpowerCAD solution library. Users can also save their designs using this tool to build ...

Its original trimpot was replaced with a multi-turn pot for ease of control. To make everything work, a load resistor on the 5V circuit makes the power supply think it’s hooked up to a motherboard.

The very popular Microchip Application Note AN954 shows a circuit ground (0 V), but the reference is silent about whether it can be connected to the main power supply’s earth ground. 1 Similarly ...

The overall power supply achieves an efficiency of 78%, an impressive feat for such a simple flyback supply delivering 3.3 V at 2 A. For most applications, the cost and simplicity may well be the ...
