The ADP2323 DC-DC converter is designed to deliver two output voltages with specified maximum output currents. The first channel provides a 5-volt output with a maximum current of 2 Amperes, while the second channel supplies 1 volt with a...
A reliable full bridge driver is essential for driving a flyback transformer. While many flyback driver schematics exist, most lack durability. The well-known Zero Voltage Switching (ZVS) driver, invented by Vladmiro Mazilli, is recognized for its reliability due to...
An AC mains operated single LED flasher circuit is constructed using the widely utilized CMOS timer chip TLC555. The entire circuit is powered directly from the 230VAC grid supply via a capacitive potential divider and associated components. This compact...
Features: 3-12 V, 1 A, over-current protection. This is a simple yet reliable device based on one of the oldest integrated voltage regulators, the LM723. R2 sets the output voltage. The maximum current is determined by the value of...
The circuit consists of three identical basic stages, with the second stage featuring a differential output from the power MOSFET, 2SJ77. A current mirror circuit utilizing 2SK214 is implemented. The operating current is 6mA; however, due to the power...
This preamplifier features a built-in regeneration control that enhances gain selectivity. CI represents a single or multi-gang AM broadcast-band tuning capacitor, while LI is a ferrite loop antenna tapped at approximately 15 to 25% of the total turns. This...
