The step-down DC-DC Converter project presented here provides 3.3V @ 1A output from an input range of 8V to 36V DC. The adjustable current limit is an important feature of the project, which prevents the device from accidental output short circuits avoiding excessive load damage. The...

The project demonstrated here is a small-size solution, high-efficiency, low-cost, and low-EMI step-up DC/DC module for LDO regulator replacement. This small size module helps save on solution size and cost while also eliminating the need for a heatsink. The module takes up the same...

This is a Smart Dual Coil Latching Relay that can control the ON/OFF power of a device by applying a short voltage pulse to Input 1 and Input 2. This project is helpful in low-power applications since the coil is not powered all the time, it only requires a short voltage pulse. Relay...

This is a Line Driver project. This single-ended-to-differential line driver is designed for high-speed communications. Using current feedback for greater bandwidth, this project delivers full-power bandwidth up to 405MHz and features slew rates as high as 6500V/µs. The MAX4447 has a...

The voice echo or digital delay sound effects project presented here is suitable for applications such as Karaoke, multimedia, musical instrument effects, electronics toys, animatronics, etc. The project is based on PT2399 chip, with an operating supply of 5V DC, and approx. 30mA...

The project presented here is a differential line receiver that offers unparalleled high-speed, low-distortion performance and is ideally suited for digital, video, and RF signal-processing applications. These receivers offer a small-signal bandwidth of 550MHz and have a high slew...

The project presented here is an over-current trip switch. It provides protection to a load when over current condition occurs. Basically, the project trips the relay when there is a short circuit or the load starts drawing much current. When the condition is favorable, press the...

This is a compact size, mono, switch-mode (Class-D) audio power amplifier intended for multimedia and general-purpose high-power applications. It has greater than 87% efficiency and is capable of delivering 2W maximum continuous power to a 4Ω load. The project is designed to be...
