Regarding TPS5621 simulation, i am using Pspice-TI. I got the library on the Pspice and build the circuit.
I want to AC simulation to get the bode plot. before that i did transient one first to make sure the circuit is working.
But there is no error on simulation but it seems not working. No output and no switching.
Has anybody seen this kind of issue ?
Please advise me.
Thanks,
Moon
