.. Can I produce a compact, ultralow noise, phantom powersupply (48 V) from a 5 V, 12 V, or 24 V input? Answer: You can, using a simple boost converter, a filter ...
.. switch-mode power supplies use “kick-start” circuits to initialize their offline operation. These circuits may be ... .. 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 ...
.. This is a simple and fully automatic, 12 V uninterruptible power supply system for small/medium power appliances (Figure 1). This powersupply specifically designs to drive ...
.. you sometimes need an inexpensive precision power supply? This Design Idea presents a precision powersupply that has thermal overload protection and short ...
.. the micro-controller included in many systems these days? This design uses microcontroller feedback to produce a 50-V, 1-W powersupply (see Figure 1). It leverages an unused analog-to-digital converter (ADC) input and a ...
.. V converter's On/Off pin remains floating when U2 is off. Figure 1. Adding an optocoupler (U2) and a resistor to this power circuit is all that’s needed to ensure the proper startup sequence of the 3.3- and 5-V converters. When ...
.. VCRs, TVs, and other equipment that requires a standby mode, you must supplypower to a µP when other components are asleep to receive and interpret any wake-up signal from the remote ...
.. article describes a portable breadboard-friendly adjustable power supply, designed as an ideal supply for Arduino projects and other low-power circuits. It is capable of ...
.. One of these TAoE improvements addressed the fact that PWM DAC accuracy tends to be limited by dependence on digital logic power supplies which, as H H aptly point out, “are notoriously inaccurate.” Their clever fix (see Figure ... .. analog switches and an accurate voltage reference to the usual PWM topology, thus isolating the DAC output from logic supply inaccuracy. One switch generates a precision version of the usual PWM waveform while the other generates its ...
