LM5025A: Recommend suitable part

Sulyn ZHANG

Part Number: LM5025A
Other Parts Discussed in Thread: UCC2897A

Hi Team,

My customer used our LM5025A in old products. Now customer kicked off a new project, but they hope to choose a part with similar function as LM5025A to realize 15V to isolated 30V application, but LM5025A oscillator frequency will vary from 175kHz to 225kHz(In whole temp range), about 50kHz variation. My customer hope to find a part with a smaller variation, see less than 10kHz or 15kHz. Could you pls help check if we have best fit part to meet customer requirement.

Best regards,

Sulyn

Hi Sulyn,

I checked the UCC2897a and it has similar oscillation variation over temperature about +/-10% compared to the LM5025A which is at +/- 12.5%.

What part of the power stage design is the range of the oscillator frequency impacting ?

Regards

Peter
