We see from your search that you're looking for information on the term "SMPS", and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest. Let me be your guide.

Start with the news release Capacitors stack up military reliability from Kemet Electronics Corp, which we summarised at the time by saying "SMPS stacked capacitors are an excellent choice for electrical applications, general purpose applications and high-frequency power supply circuits". A few weeks before, we featured the news release Dual operating modes boost controller flexibility from STMicroelectronics: "The L6566 selectable multimode controller is suitable for applications such as flyback AC/DC adapters, TV and LCD monitors, small size LCD TVs, high end chargers and other consumer equipment".

In October 2007, we covered the news from Microchip Technology concerning its MCP1631 PWM - take a look at Pulsewidth modulator closes feedback loops which says: "Designers can use the MCP1631 2.0MHz to perform many different functions in their designs, cutting footprint and cost".

Take a look also at the news release from Fairchild Semiconductor, Speedy diodes smooth out LCD TV supplies, as well as Current clamps extend power measurement from Fluke (UK), and Online design centre supports PSU design from Texas Instruments (April 2006-).
