TPSF12CX-DESIGN-CALC: How to understand the meaning of the tool

Part Number: TPSF12CX-DESIGN-CALC

Hello, 

I have some trouble with the design tool "TPSF12CX-DESIGN-CALC". 

1.Which picture should I use to determine the unstable frequency and how to determine it?

2.The column for unstable frequency in the table is in red. What does this mean?

3.How to understand the picture "AEF Gain for Attenuation Performance"?Why does magnitude have both positive and negative one?

Thanks.

  • 您好,   

    1. 我们不建议使用低于 65kHz 的任何开关频率。

    2. 红色频率表示不建议使用此值 - 这会增加电压饱和的机会。

    3. 这意味着它将是衰减,而不是提供增益。理想情况下,我们建议在 150kHz 至 3MHz 之间的工作区域内 - 我们希望 AEF 增益为正。
