LMZM33602: Check Stability of LMZM33602 in TINA

Part Number: LMZM33602
Other Parts Discussed in Thread: LMZ34002, , TPS84259

I want to simulate (AC analysis) of LMZM33602 and LMZ34002 on TINA to see Bode plot and check stabilty of module. But I couldn't do it. From examples i learned that for AC characteristics of power modules i need average model. Please help me in this regard. Thanks

Hi Ahsan,

Unfortunately there is only the transient mode available online.

I would suggest using the TI WEBENCH Designer tool to generate the simulation on the "SIMULATE" tool and "Bode Plot" option.

Regards,

Jimmy

Thank you Jimmy for your reply. Yes You are right but for other modules like LMZ34002 there is no Bode plot option in 'SIMULATE' in TI WEBENCH Designer tool.

In lieu of the LMZ34002 not having a bode plot simulation on WEBENCH designer tool, I've attached an excel calculator for bode plot for your reference.

Please not that the TPS84259 and LMZ34002 are the same part. This should help provide some guidance on frequency response of the LMZ34002.
