An Electronicstalk guide

Start with the news release DC/DC uModule PoL regulator for RAID systems from Linear Technology, which we summarised at the time by saying "The LTM4611, a complete switch mode DC/DC uModule point-of-load regulator, is suited for applications in systems with only 3.3, 2.8 or 2.5V as the main power rail.". Several months prior to that, we featured the news release DC/DC converter for inverting power supply apps from Linear Technology: "Linear Technology has announced the LT3957, a DC/DC converter for boost, flyback, SEPIC and inverting power supply applications.".

In November 2010, we covered the news from Linear Technology - take a look at DC/DC converter suits medical and telecom sectors which says: "The LT3958 from Linear Technology is a high input voltage DC/DC converter for boost, flyback, SEPIC and inverting power supply applications in the industrial, automotive, medical, and telecom sectors.".

Take a look also at the news release from Intersil, DC/DC power module designed for defence, as well as Buck regulator includes low-resistance switches from Linear Technology, and Buck regulator ideal for single-cell li-ion apps from Linear Technology.
