摘要
Examples to control timing for current-mode boost converters are disclosed. An example device to control timing includes a first input terminal to receive an input voltage of a current-mode boost converter a second input terminal to receive an output voltage of the current-mode boost converter, a generator to generate a first timing signal from the input voltage and the output voltage, a third input terminal to receive a second timing signal from the current-mode boost converter, a selector to select between the first on_off time signal and the second on_off time signal to generate a third on_off time signal based on a comparison of a first off time duration of the first on_off time signal and a second off time duration of the second on_off time signal, and an output terminal to control off times of the current-mode boost converter based on the third on_off time signal.
