Duty cycle of buck boost converter
Webdecrease the input voltage, depending on the duty cycle D; hence the name "buck-boost". For example you can regulate to an output voltage of –5 V from an input voltage of from 5 V … WebAug 18, 2024 · Be aware that boost converters really suffer for efficiency at high boost ratios, and a flyback might be a better choice if you expect always a similar boost ratio. The transformer ratio can also put you more toward a 50% center duty cycle vs line / load / make / temp. I'd bet that you can find plenty of well modeled, suitable core capacity
