Hi,

Could you tell me the maximum output capacitance that can operate stably.
Customers want to know can be added to what extent ceramic capacitor.

Hello Yusuke-san,

The lowest LC corner frequency is around 5KHz. Once you select the inductance value, the output capacitance can be easily calculate.

Hope this help.

Kit-san,

Thank you for your response.
My customers are planning to use 1uH.

Yusuke-san,
The L/C values also need to calculate to meet the load transient specifications.
