Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A design team needs to evaluate two different MOSFETs for a PWM application. MOSFET A has a switching loss of 1.5W and conduction loss of 5W at a given frequency. MOSFET B has a switching loss of 2W but a lower conduction loss of 2.5W. Which one should they choose for efficiency and why?

💡 Hint: Compare overall power dissipation to conclude efficiency.

Challenge 2 Hard

Explain how rise time and fall time affect the efficiency of a high-frequency power supply circuit. Provide examples involving specific components.

💡 Hint: Consider real-world component datasheets for specific rise and fall times.
