.. protection is an obvious requirement for a power supply, especially when its load connects to a cable that's subject to damage. Many modern power-converter ...
.. The transistors are preferably Darlington types and, like the diodes, should have adequate ratings to accommodate the power-supply voltage and the motor current. (Don't forget the high inductance of the motor.) The components in ...
.. 1 shows an example of on/off circuitry commonly used in battery-operated devices. The p-channel MOSFET, Q 1 , serves as a power switch. When you push the On button, S 1 , Q 1 ’s gate goes low. Q 1 turns on and supplies battery ...
.. and thermoelectric coolers. Their resistance can change more than 100% during operation, and the result is a change in power dissipation for elements receiving drive from a fixed voltage or current source. Worse, excessive power can ...
.. free energy collector circuit helps to convert surrounding radio frequency waves to electric power and can provide 40 watts to 10 watts indefinitely. The circuit concept An option to increase the output power ...
.. approach of backing up a DAC with an amplifier to boost output, this design idea charts a less traveled by path to power. It integrates an LM317 positive regulator with a simple 8-bit PWM DAC topology to obtain a robust 11-V, 1.5-A ...
.. voltage inverter. Shortly thereafter the idea morphed into an uncomplicated, inexpensive, and fairly fast (1 MHz), low power voltage to frequency converter (VFC) “Voltage inverter design idea transmogrifies into a 1 MHz VFC” ...
.. If the lowest possible noise is important, you can use lower resistor values, but that’s at the expense of higher power consumption and increased distortion. The LM49710 distortion performance is specified with minimum load ...
.. a flat, wideband response, and an output matching network including the transmission line to the output connector. The power supply block uses a charge pump and dual low-dropout (LDO) voltage regulator to supply positive and negative DC ...
.. dummy-load circuit has been in use at Maxim for more than 10 years (see the Figure 1). It's useful for testing power supplies and power amplifiers as well as drivers for LEDs, relays, and solenoids. Plus, it overcomes the ...
