Energy Efficiency Becomes the Focus for Data Centre Servers

Posted on 02 July 2012

      This architecture is also favorable for future improvements The significant growth in power consumption for information technology (IT) data centres has created an excellent opportunity for companies to develop products focused on energy efficiency. By Arman Naghavi, Vice President and General Manager of the Analog and Power Division, Integrated Device Technology, Inc.   [...]

Integrated All-in-One Buck Converters Make for Great Macros

Posted on 02 July 2012

      High current gate drives, coupled with optimum dead times yield higher efficiency Low power Point of Load (POL) Buck Regulators have evolved dramatically, particularly in netcom and storage markets. While consuming less power than CPU’s, function specific ASICs, impose ever tighter accuracy and space constraints as well as mandating special features. By [...]

3-Level Inverter – Easy Online Dimensioning

Posted on 02 July 2012

      Inverter manufacturers can quickly decide which topology and which module In inverter development – whether 2-level or 3-level topology – an important step at the outset is correct dimensioning for module power, cooling system and driver. Due to the greater number of switches in the current path, the 3-level inverter circuit has [...]

Inrush Current Limiters (ICL)

Posted on 02 July 2012

      Inrush Current Limiters (ICL) PTC and NTC thermistors limit turn-on currents Inrush Current Limiters based upon PTC and NTC technology assist in limiting turn-on currents in capacitive and inductive loads so that line fuses do not operate. By David Connett, Director IC Reference Design EPCOS AG, A Group Company of TDK-EPC Corporation [...]

A Practical Method to Extract and Visualize Real Time Frequency of a Switching Signal on an Oscilloscope

Posted on 02 July 2012

      Application to the observation of the clock dithering feature of TPS62674 In the domain of switching converters, frequency is often of a concern in terms of, for example, efficiency, stability or induced noise in the application. Being able to know the frequency characteristic of a given output signal gives often a lot [...]
