These regulators provide all the active functions for a step-down buck switching regulator, capable of driving a 1-A load current with excellent line and load regulation. These devices are available in fixed output voltages of 3. PDF , 1. Extract from the document. PDF , PDF , Kb , Revision: B , File published: Apr 23, This application report provides design information to help select an off-the-shelf inductor for anycontinuous-mode buck converter application.
These regulators are simple to use and require only a few externalcomponents. In this article the design of a polarity inverting converter will be discussed. PDF , 3. It will discuss several variations of a layout analyze the results andprovide answers to some common EMI questions such whether or not to use a shielded inductor.
PDF , 2. The method is explained in an easy to followstep-by-step manner so that a power supply designer can start performing these measurements in a shortamount of time.
Using agood layout can solve many problems associated with these types of supplies. The problems due to a badlayout are often seen at high current levels and are usually more obvious at large input to output voltagedifferentials.
Some of the main problems are loss of regulation at high output current. In switching power supplies EMI noise isunavoidable due to the switching actions of the semiconductor devices and resulting disconti. PDF , 9. This becomes more critical for packageshaving very low thermal resistance between junction-to-case such as exposed pad TSSOP.
LM2675 Buck Converter overview
These regulators provide all the active functions for a step-down buck switching regulator, capable of driving a 1A load current with excellent line and load regulation. These devices are available in fixed output voltages of 3. Requiring a minimum number of external components, these regulators are simple to use and include patented internal frequency compensation Patent Nos. The LM series operates at a switching frequency of kHz, thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. A family of standard inductors for use with the LM are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies using these advanced ICs.
