Part Number: TPS548B28
Other Parts Discussed in Thread: TPS548A28

Hi Expert,

The end customer is defined the 15k~300khz range need to met for unity-gain bandwidth of TPS548B28.

Not defined the switching frequency.

Can you advice how to meet this?

Best regards,

To meet the requirement, folllow the design procedure in datasheet, webench or excel sheet on product folder.

Use the simplis model and run an AC simulation to check it or measure on bench using network analysis.

The TPS548B28 is similar to TPS548A28.

the datasheet for TPS548A28 has a bode plot https://www.ti.com/lit/ds/symlink/tps548a28.pdf#page=37 in figure 8-34 The crossover frequency is ~65kHz for that design
