TPS54228: About Recommended Component Values

Part Number: TPS54228

Hi team,

My customer is designing the circuit of this device and have some questions about it.

In the datasheet, there is a table about the recommended component values.

If the output voltage is 1.8V or 3.3V, even if the customer's typ output current is low and the device is always in the power save mode and the SW frequency alters, are the recommended C and L value still 22~68 uF and 3.3uH?

  1. Is there any other factors that effects the recommended inductor value rather than the output voltage?
  2. Is the recommended value for the output capacitor always be 22uF~68uF for all the SW frequency range?

Regards,

Ohashi
