We see from your search that you're looking for information on the term "Adjustable output voltage",
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 Convertor copes with green energy standards from
Advanced Analogic Technologies, which we summarised at the time by saying "Synchronous step-down DC/DC convertor offers power savings in a variety of industrial applications, especially those using backplanes".
A couple of weeks before,
we featured the news release DC-coupled amp allows sensitive measurement from
Laser Components (UK): "Laser Components has expanded its amplifiers portfolio with the HCA-400M-5K-C high-speed current amplifier from Femto".
In July 2007, we covered the news from Sunpower (UK)
concerning its ELN-60 Series
- take a look at LED power supply saves on PFC
which says: "Switching power supply for low-cost lighting applications features IP64 design, protecting components from dust and moisture in harsher locations".
Take a look also at the news release from Microchip Technology, Switcher chip cuts handheld power drain,
as well as Supplies are made for LED lighting from Sunpower (UK),
and Step-up charge pumps cut quiescent current from Linear Technology Corp.
