Is it possible to combine or tie together the TRACK/SSx pins of a 2x LTC7890 (Parallel) single output configuration?

Question

Accepted Answer

Answer: 
 In a design where two separate LTC7890 single output configurations are used in parallel, it's important to separate the Soft Start Pins (TRACK/SSx). This ensures that the soft start (SS) pins for both channels remain independent, preventing one channel from influencing the soft start sequence of the other. The TRACK/SSx pin on the LTC7890 has an internal ALL OFF switch, which, when engaged, will also affect and discharge the Soft Start Capacitor (Css) of the other controller.
