Hello, I have several questions regarding Tina and Spice model: LMR23610A Unencrypted Non-Inverting and Inverting PSpice Transient Model
1. When loading the model this message is returned " More than one subcircuit exists or models found in the file" How is this corrected?
2. Can the noise of the LDR be simulated?
3. .SUBCKT LMR23610A_TRANS SW BOOT VCC FB EN_SYNC AGND VIN PGND PAD PARAMS: MODE=0, what does mode refer to?
thanks
Hi,
1. Which program are you using to load this model? If using PSPICE for TI, these tutorials should help when loading models into PSPICE: www.ti.com/.../6162754989001
2. These are the stated simulation profiles we have available for this
In order to simulate noise on a specific circuit, please take a look at this thread for more information: Simulating Noise
3. I am not sure but the "Mode = 0" is likely to do with the circuit's creation and is a variable set to make sure the model works as intended.
Thank you,
Joshua Austria
Importing the model into LT spice:
The 3.3V output is ripple-free/ void of noise and the SW pin is DC. Can you check the model on your end to confirm my results? When the MODE = 0V, the
the output is 0V.
thanks
Hi,
Mode is a parameter to reach the output faster. Mode = 0 will give a startup waveform, and Mode = 1 will give a steady state waveform. The output should be 3.3 V. This is the startup waveform that I got running the associated circuit in PSPICE for TI.
Please be advised that these models are not guaranteed to work with LT Spice and TI only officially supports PSPICE for TI
Thank you,
Joshua Austria
