TPS40345: Please tell me how to change the load

Tishida

Part Number: TPS40345

I want to simulate ripple caused by load fluctuation.

I want to do a simulation that changes the load like 5V/5A -> 5V/8A -> 5V/5A

(Image USB type c load)

Is this in PSpice or in WeBench?

In PSpice, you will need to add a Current Source to the load, either a Piece Wise Linear current Source or a Pulse current Source.

Set the loading resistor for 1Ω (5A @ 5V) and the current source to create the 2A loading transient that you are looking for.

In WeBench, under Simulate, select the "Load Transient" option.
