  Compensation Made SIMPLE With LM4360x, LM4600x
  PDF, 457 Kb, Archivo publicado: jul 29, 2014
  Compensating a DC-DC buck converter is challenging if the designer is not familiar with the loop control theory. To achieve a stable design under all corner and adverse conditions, the user must properly compensate the regulator. While DC-DC converters with external compensation provide flexibility, they increase complexity. The LM43600/1/2/3 and LM46000/1/2 are a family of Wide VIN, fully-synchro

  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
