Schematic diagram below shows an ADP1821 Step Down DC-to-DC Converter circuit. This circuit uses ADP1821 that can be used to regulate an output with a load of more than 20 A. It can be done if he power components like MOSFETs, the bulk capacitors and the inductor are chosen carefully to achieve the power requirement. The power-train component limits the […]

This is a power on circuit that works temporarily only when the power is turned on, this LED illuminates for a few seconds, then turns off again. This design is eco-friendly since it consumes only a little power at the beginning of the power connection. Here is the schematic diagram of the circuit: The circuit uses the 47uF capacitor that […]

This is a voltage multiplier circuit. First circuit is used to double the a square wave (any amplitude). However there is minus about 2v losses in base-emitter of the transistors and the diodes in first circuit. To work, second circuit must fall to nearly 0.4v and rise to at least 5.6v. to prevent short-circuiting and both transistors coming on at […]
Read moreThe circuit of battery monitor below uses 3 separate LEDs. Voltage level between 6v to below 11v will turn the red LED on and will turn off above 11v. Between 11v and 13v will turn the orange LED on and will turn off above 13v. The green LED illuminates above 13v. [Source: talkinglelectronics.com]
