Other Parts Discussed in Thread: LM3445

Hi,

Can you help me to understands the differences between LM3445 and LM3448?

As my understanding, the difference is only MOSFET integration.

If it's right, almost all circuits should be same, and design guide for LM3448 should be applicable for LM3445 as well.

AN-2090 LM3448 -120VAC, 6W Isolated Flyback LED Driver

Hi Ken,

Yes, you are right. They are almost the same except the package and FET. They can achieve similar dimming performance.

I think it 's better to follow the device's own design guide as driver size and cost will affect customers' decision.

Best regards,

Victor
