Other Parts Discussed in Thread: TPS54610, TPS54680, TPS54227, TPS54550, TPS54527, TPS54620

We have a qurstion about tracking by buck DCDC.

We set to start up two output voltage at the same time(tracking) by connecting Vout of TPS54610 and taracking pin of TPS54680.

We want to set tracking by TPS54227 or TPS54550.

DO you have any information to set tracking about TPS54527 or TPS54550?

We want to start up two output voltage at the same time.

But TPS54527 and TPS54550 don't have the TRACKIN pin.

Best regards,

Nishizawa-san,

let me think about this. There may be an undocumented way. I'll get back to you soon.

Nishizawa-san,

Tracking with TPS54550 will be problematic as it is a dual function SS/ENA pin. There is some dc offset. Can you tell me about your application and power requirements? If you are already using TPS54610 series, can you use TPS54620 instead of TPS54527?
