Design Considerations for DC-DC Converters in Fast-Input Slew Rate Applications
PDF, 191 Kb, File published: Mar 5, 2015
This application report describes the ways to optimize the design of DC-DC converters (TPS54040-Q1, TPS54060-Q1, TPS54140-Q1, TPS54160-Q1, TPS54240-Q1, TPS54260-Q1, TPS57040-Q1, TPS57060-Q1, TPS57140-Q1, and TPS57160-Q1) in applications with fast transition at the input voltage on the rising and falling edges. First, the issues faced under such a scenario are analyzed. Then, design considerations
