  • Thermal Design Made Simple With LM43603 and LM46002
    PDF, 535 Kb, 档案已发布: Sep 15, 2014
    This Application Report will walk through the thermal design of power supplies using the LM43603 and LM46002.In the process we will cover common tips and approximations to speed up your design.
  • Compensation Made SIMPLE With LM4360x, LM4600x
    PDF, 457 Kb, 档案已发布: 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
  • Low EMI Layout Made SIMPLE With LM43600/1/2/3 and LM46000/1/2 (Rev. A)
    PDF, 512 Kb, 修订版: A, 档案已发布: Sep 12, 2014
    Printed Circuit Board (PCB) layout for Switched Mode Power Supplies (SMPS) is critical to achieve proper converter operation good thermal performance and excellent radiated EMI performance. Optimized board layout for low radiated EMI is made very simple by the package and pin arrangement of the SIMPLE SWITCHER Synchronous Buck Converter family LM4360x and LM4600x
