This also implies that there is not much space available for extensive cooling mechanisms like fans or heat sinks. The designs are often battery powered, so operating at high efficiency to get maximum operating time at one battery charge is also important. This usually can be achieved by powering the circuits using switch-mode power supplies.</span></p><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;font-size:12pt;">The switching operation of the switch-mode power supplies typically generates noise. Because of this it can be challenging to design a reliable power supply circuit especially if a highly sensitive sensor or any kind of radio is part of the design. Limited space usually does not allow the use of large components for filtering and protection.</span></p><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;font-size:12pt;"> </span><span style="font-family:arial, helvetica, sans-serif;font-size:12pt;">This presentation uses practical examples of applications that show different approaches for minimizing noise and improving robustness in a low power design when using switch-mode power supplies.</span></p></td></tr><tr><td style="border:1px solid black;border:1px solid #000000;padding:2px;"><span style="font-size:12pt;font-family:arial, helvetica, sans-serif;">About the Presenter </span></td><td style="border:1px solid black;border:1px solid #000000;padding:2px;"><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;font-size:12pt;"><span lang="EN" style="color:red;">Jürgen Neuhäusler, Texas Instruments <br /></span><span lang="EN">Senior Applications Engineer for ALPS (Advanced Power Solutions, Low Power DCDC Converters)</span></span></p><p style="margin:0;padding:0px;"> </p><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;font-size:12pt;">Jürgen Neuhäusler is Senior Applications Engineer for Advanced Low Power Solution devices at Texas Instruments, based in Freising.
