Challenge Problems
Push your limits with advanced challenges
A DC-DC converter needs to output 12V with a switching frequency of 100kHz. If the input voltage is 15V, calculate the required duty ratio.
💡 Hint: Remember, output voltage cannot exceed input voltage.
Explain how you would design a feedback loop for maintaining the output voltage at 5V despite varying loads and input fluctuations.
💡 Hint: Focus on how feedback corrects the output to meet demands.
