    Certain applications require that output voltage regulation be maintained when the input voltage is only slightly higher than the output voltage. For a buck converter, these low headroom operating conditions require high duty cycle operation that may approach 100%. As the converter on-time duration approaches the switching period, the charge on the BOOT capacitor must be maintained in order for th

    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
