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, LM4600xPDF, 457 Кб, Файл опубликован: 29 июл 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 Кб, Версия: A, Файл опубликован: 12 сен 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
