Automotive batteries, industrial power supplies, distributedsupplies and wall transformers are all sources ofwide-ranging high voltage inputs. The easiest way to stepdown these sources is with a high voltage monolithicstep-down regulator that can directly accept a wide inputrange and produce a well-regulated output. The LT®3493accepts inputs from 3.6V to 36V and LT3481 acceptsinputs from 3.6V to 34V. Both provide excellent lineand load regulation and dynamic response. The LT3481offers a high effi ciency solution over a wide load range andkeeps the output ripple low during Burst Mode® operationwhile the LT3493 provides a tiny solution with minimalexternal components. The LT3493 operates at 750kHzand the LT3481 has adjustable frequency from 300kHzto 2.8MHz. High frequency operation enables the use ofsmall, low cost inductors and Ceramic capacitors.

A recent trend in the design of portable devices has beento use Ceramic capacitors to filter DC/DC converter inputs.Ceramic capacitors are often chosen because of theirsmall size, low equivalent series resistance (ESR) and highRMS current capability. Also, recently, designers havebeen looking to Ceramic capacitors due to shortages oftantalum capacitors.

Abstract: The reality of modern, small form-factor Ceramic capacitors is a good reminder to always readthe data sheet. This tutorial explains how Ceramic capacitor type designations, such as X7R and Y5V,imply nothing about voltage coefficients. Engineers must check the data to know, really know, how aspecific capacitor will perform under voltage.

As a student I did my best to avoid text books – a strange statement for a Professor to make and one that I should clarify before you put this book down; I did my best to avoid text books that did not help me.

The PW5200A/ PW5200C is high efficiency synchronous, PWM step-up DC/DC converters optimizedto provide a high efficient solution to medium power systems. The devices work with a 1.4MHz fixedfrequency switching. These features minimize overall solution footprint by allowing the use of tiny,low profile inductors and Ceramic capacitors. Automatic PWM/PFM mode switching at light loadsaves power and improves efficiency

v> 目前最常見的藍(lán)牙天線有偶極天線（dipole antenna）,倒 F 型天線（planar inverted F anternna）、曲流線型天線（meander line antenna）、微小型陶瓷天線（Ceramic antenna）、液晶 聚合體天線（lcp）和棒狀天線（2.4G 頻率專用）等。由于這些具有近似全向性的輻射場(chǎng)型 以及結(jié)構(gòu)簡(jiǎn)單、制作成本低的優(yōu)點(diǎn)，所以非常適合嵌入藍(lán)牙技術(shù)裝置使用。
