TPS62811-Q1: Output Impedance Plot Across Freq to Bandwidth of Regulator

Robert Eschler

Part Number: TPS62811-Q1

Do you have an output impedance plot across frequencies up to the bandwidth of the regulator? For our design, we are operating at 2.2MHz.

Hi Robert,

Currently, we don't have any impedance plot evaluated for this device.

Is there any application concern that requires these measurements?

Best regards,

What is the bandwidth of the output, and do you have an plots that shows the frequency response?

Hi Robert,

You can simulate the frequency response through the simulation model. SIMPLIS model has an AC model that will help to rum frequency response simulation.

The bandwidth can be evaluated from transient/ frequency performance with your configuration. The app note explain show how it can be calculated from transient performance: https://e2e.ti.com/blogs_/b/powerhouse/archive/2016/11/22/how-to-determine-bandwidth-from-the-transient-response-measurement
