Part Number: TPS56121 Tool/software: Hi, I would like to use the TPS56121 converter as an adjustable constant current source for a nonlinear load (diode). The target parameters are: output voltage of a maximum of 8 volts, maximum current of 12 Ampere…
Hi Aaron,
Webench is limited in terms of duty cycle, that's why you see an error for this in Webench. Referring to the datasheet, this ideally should work since the duty cycle meets the datasheet duty cycle threshold. Although in a real application, the…
Part Number: TPS56121 Other Parts Discussed in Thread: TPS56221 We added a resistor and FET 2N7002 N-CH 60V to the design to allow controlled startup and shutdown.
When the FET switch is enabled, the +5V supply does not start.
Checked part values, temperature…
Part Number: TPS56121 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.

Part Number: TPS56121 Other Parts Discussed in Thread: TPS543C20 , Hello There,
I have a quick question on the internal regulator operation depending on EN pin. Per I know, the internal regulator keeps running once VDD pin is applied with a proper level…
Try and run this file TPS56121 (3).TSC without modifications, it works for me.
The (3) file is the file from original post with the modifications discussed in my 1/11 post.
Does it simulate and yield a result
If not, Let us troubleshoot your simulation…
Part Number: TPS56121 Other Parts Discussed in Thread: TPS56221 Hi Team,
The TPS56121 is rated up to 15A as stated at page 1 of the datasheet. However, it states in section 8.2.2.12 it can handle 20A. Our customer would like to know how does this affect…
