Part Number: TPS563207

Hi TI Team,

1. Can you please clarify difference between TPS563207 and TPS563207S ?

2. Is there any limitation on Max output capacitance?

3. For good stability of the converter, any criteria need to be ensured?

thank you,

Johnson John

Hi Johnson

1. Only one difference, 207S has higher Vref accuracy(1.5%) and 207 is 2%.

2. Recommend to use following the range in the table.

3. Good stability is judged differently by different customers. a method commonly used to evaluate stability, the Bode plot test, with a bandwidth less than 1/3 the operating frequency and a phase margin greater than 45°. thanks!
