TPS563209: Requirement of Output capacitance on Buck converter IC TPS563209

Part Number: TPS563209

Dear TI experts




We are using TPS563209 Buck converter IC in most of our products.


In one of our applications, we have generated 5V output from 12V input using TPS563209.  


Referring to Datasheet  SLVSCM5A –SEPTEMBER 2014–REVISED NOVEMBER 2016, page 14 in the following table, Recommended component values, the maximum output capacitance is 68uF (C5+C6) .

As you know capacitance of ceramic capacitors changes with DC bias.

For 5VDC a 10uF/16V X7R capacitor would exhibit 6.5 - 6.7uF capacitance.

To achieve this I need to put 10nos of 10uF capacitors on output.


Can I put a larger single 100uF aluminum low ESR capacitor?

Is there any limitation for maximum capacitance on output?

Will there be failures of IC if output capacitance is too much than recommended in the datasheet?
