Other Parts Discussed in Thread: LM5122
I am using LM5122 for start-stop application. I developed pcb and tested. Used PMP7936 LM5122 reference design. Its below.
Design is working . But i have a problem. When the frequency value is 250 KHz, fets are warming up to 100°C. I solved this problem by reducing the frequency. I couldn't find anything about the minimum frequency.
I want to learn;
* Is it correct to lower the frequency to reduce warming?
* What is the advantage-disadvantage of low / high frequency?
* What else can be done to prevent overheating at high frequency? (I change snubber components. Another else?)
