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 - Methods to Improve Low Dropout Operation with the TPS54240 and TPS54260 (Rev.

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
