Other Parts Discussed in Thread: TPS53315

Dear support member,

My customer use TPS53315.

At the resistor connected to the MODE pin,
recognize that I can set the soft start time.

When connected via a 100kΩ to PGOOD pin,
What percentage of about ± with the exception of the resistance error or will those that occur?

Could you teach a formula to realize the 1.4ms with a resistance of 100kΩ?

Best Regard.
Bob Lee.

The soft start times are "fixed". There is no equation for them. The datasheet only lists typical times. There may be some tolerance data for it. I can check next week.
