.. platforms for all sorts of useful power supplies. A $1 three terminal regulator and 3 capacitors will make a nice DC power supply. But for analog instrumentation and mixed analog-digital circuits it’s often much easier to design and ...
.. TinyUPS is a simple 5 V/2.5 A uninterruptible power supply with a li-ion battery as a buffer, a load sharing power path management system and an ATtiny13 for monitoring ...
.. Adzic - Serbia Montenegro Description A novel supply voltage monitor which uses a LED to show the status of a power supply. Notes This simple and slightly odd ...
.. way to connect multiple batteries or dc power supplies to a load. With a forward-biased “or” diode between each supply and the load, faults are isolated. Weak, low, or shorted supplies can’t sink current from the other ...
.. or two capacitors filter into dc. The battery (not shown) is a 12 V lead-acid type. IC1 compares the battery voltage to the supply voltage. When the rectified voltage drops below the battery voltage, the battery takes over to provide LED ...
.. where the current sense shunt resistor is connected in series with load at the negative voltage rail. It needs only one supply voltage that can be acquired from main PSU. An additional function of the multimeter is that it can control ...
.. Palazzolo Get 1.25V to 3.75V from an adjustable regulator Every PC has a USB (Universal Serial Bus) port that can supply 5V 5% at 500 mA for peripherals. Powered USB hubs also provide this power. You can use a USB port to power an ...
Limiter circuits are often needed to prevent a wide-range signal from overloading the next stage in the signal chain this user-adjustable circuit provides bipolar limiting at precise preset value. As the name implies, a limiter circuit (sometimes ...
Input voltage from high voltage DC DC converter is 12V AC at 800mA current and then converted to DC through a bridge rectifier Diode 1A. The voltage output of converter circuit can be adjusted in the range of 0-1000V DC. This high voltage DC DC ...
