100W LED driver evaluation board using high-frequency LCC transformer to achieve low-cost and miniaturized design

This 100 W reference design highlights the excellent power quality and high frequency performance of the half-bridge (HB) driver using the ICL5102 with the economical CoolMOS™ P7 series. The design takes full advantage of the applicable frequency range of the HB driver to create Highly compact LCC transformer. This transformer integrates the series inductance of the LCC resonant tank. Relying on this high power density transformer design, the high frequency operation capability can drive system cost and size reduction.

Magically modify your computer power supply to make a beautiful desktop power supply, simple and practical

You can certainly buy desktop power supplies, but they're not cheap. As the current capacity and output voltage quantity increase, so does the price. While a commercial desktop power supply is certainly worth the investment, you may want to consider a cheaper solution. Adapt an old computer power supply for use on your workbench. Computer power supplies have all the voltages you need and some very impressive current capabilities.

snapVCC: 3.3/5 V ultra-efficient voltage regulator that mounts directly on your 9 V battery (schematic, PCB, etc. included)

snapVCC is a highly portable and convenient power supply for your electronics projects. It's designed to fit a 9V battery and provide you with 3.3V or 5V power wherever you need it. What can you do with snapVCC? Many circuits require a regulated 3.3 or 5 volt power supply. 9V batteries are an easily available power option. A common method of using a 9V battery to power a circuit is to use a linear regulator IC circuit to step down the voltage.
