TPS62800: Bode Plot

Danilo A.

Part Number: TPS62800

Hi Team,

A customer would like to request for a bode plot of the schematic diagram at Figure 7 of the User' guide of TPS62800EVM. Do we have this information?

Hi Danilo,

There are 3 boards on that User's Guide. What particular device (TPS62800/801/802) the customer want to have the bode plot measurement? And at what test condition (VIN, VOUT, IOUT)?

Best regards,

Excel

Hi Excel,

The customer needs the simulation of TPS62800.

Hi Excel,

The customer needs the simulation of TPS62800 at Vin = 1.8V to 5V, Vout = 0.7V and Iout = 1A.

Hi Danilo,

What are the output inductor and total output capacitors? Is it within the LC matrix indicated in the datasheet (see figure below)? The LC output filter combination below had been verified during the design stage to have a stable control loop (Phase margin => 45 deg.) at the entire VIN, VOUT, and IOUT ranges. Hence, the customer does not need to conduct bode plot measurement or simulation.

Best regards,

Excel
