Notas de aplicación
- Softstart Using Constant Current Constant Voltage ApproachPDF, 337 Kb, Archivo publicado: jul 24, 2015
In many systems backup power is provided either by batteries or simply by a large value capacitor. Inthese applications the capacitor would only provide the current when the primary power source fails.Further, these applications are usually for light load currents. During normal operation the backupcapacitors are kept charged up by a DC/DC converter. The challenge involved in an application - AN-643 EMI/RFI Board Design (Rev.

- AN-1082 Adjust or Synchronize LM2586/88 Switching Frequency (Rev. B)PDF, 69 Kb, Revisión: B, Archivo publicado: abr 23, 2013
Switching frequency is a very important parameter in switching power converters. As the switchingfrequency increases, the physical size of magnetic elements and other components in the circuit reducesignificantly. Switching frequency also plays a great role in control loop gain and compensation design.Switching frequency determines the maximum allowable bandwidth of the control loop. Switchi - AN-1149 Layout Guidelines for Switching Power Supplies (Rev. C)PDF, 82 Kb, Revisión: C, Archivo publicado: abr 23, 2013
When designing a high frequency switching regulated power supply layout is very important. 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 - Understanding Boost Power Stages In Switchmode Power SuppliesPDF, 149 Kb, Archivo publicado: marzo 4, 1999
A switching power supply consists of the power stage and the control circuit. The power stage performs the basic power conversion from the input voltage to the output voltage and includes switches and the output filter. This report addresses the boost power stage only and does not cover control circuits. The report includes detailed steady-stage and small-signal analysis of the boost power stage o - AN-1229 SIMPLE SWITCHER PCB Layout Guidelines (Rev.

Electromagnetic Interference (EMI) is an unwanted effect between two electrical systems as a result ofeither electromagnetic radiation or electromagnetic conduction. EMI is the major adverse effect caused bythe application of switch-mode power supplies (SMPS). In switching power supplies EMI noise isunavoidable due to the switching actions of the semiconductor devices and resulting disconti - AN-1520 A Guide to Board Layout for Best Thermal Resistance for Exposed Packages (Rev.

This thermal application report provides guidelines for the optimal board layout to achieve the best thermalresistance for exposed packages. The thermal resistance between junction-to-ambient (ОёJA) is highlydependent on the PCB (Printed Circuit Board) design factors. This becomes more critical for packageshaving very low thermal resistance between junction-to-case such as exposed pad TSSOP
