.. Sheehan EDN When you design dc/dc converters, it is often necessary to generate a bias supply to operate the control circuitry from the raw input voltage. Many methods are available for configuring the ...
.. Note [1] 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. Similarly, Apex Technology’s Application Note [2] describes circuits that cannot ...
.. Normet Electronic Design The amplifier within a standard AV receiver can become a fully adjustable, three-phase power supply by adding a general-purpose op amp, a few passive components, and some standard transformers. If you need an ...
.. complexity to isolated designs: there is propagation delay, aging, and gain variation, all of which complicate power supply loop compensation and can reduce reliability. Moreover, during startup, either a bleeder resistor or a high ...
.. Can I produce a compact, ultralow noise, phantom power supply (48 V) from a 5 V, 12 V, or 24 V input? Answer: You can, using a simple boost converter, a filter circuit to ...
.. These transistors provide the initial current for the flyback or PFC (power-factor-correction) IC. When such a power supply starts operating in normal mode, a supply voltage from a dedicated winding keeps supplying the PFC IC, thus ...
.. If you use an ADC to monitor a system's power-supply voltage, you may encounter situations in which the supply voltage exceeds the ADC's reference voltage ...
