MC78L15ABPG Original supply

The article describes a simple and very cheap to drive white, blue or UV LEDs, used for example in small lamps and testers. The cost of components shall not exceed CZK 10. Converters for white LED has been on...

This capability has wide application in battery and solar-powered systems. If the ground-referred voltage output is unloaded by an amplifier, the shunt can operate with very little voltage drop across it, minimizing losses. The LTC1043 can sense current through...

Each subsequent stage adds 1700 volts, resulting in more than 20 kV with 12 stages. However, this voltage can only be achieved when the output of the cascade is unloaded. The described circuit appears to be a high-voltage cascade generator,...

Create a small buzzer for a bicycle that emits sound intermittently to deter bears. A 12V buzzer from Radio Shack (Cat. No. 273-065) is available, and there is a question regarding the feasibility of operating it directly from an...

This power supply unit (PSU) has been designed for high-current ham radio transceivers, providing approximately 20 Amps at 13.8V. It features a secondary output capable of handling currents from 15 mA up to a maximum of 20A. The unit...

This power supply employs two VN400A 400-Volt MOSFETs arranged in a half-bridge configuration. The outputs provide +5V at 20A and +15V at 1A. Low-current outputs utilize three-terminal regulators, allowing for either 12 Volts or 15 Volts to be achieved...
