Using LTSpice to model LTC3870. The circuit uses 2 of these and NOT the LTC3880. The macromodel test fixture uses LTC3880 and LTC3870 and the control parameters are entered into the LTC3880 device. Using the LTC3870 on its own seems to work sometimes but its flakey. The problem is that it runs, then with the same values the simulation stalls.
1. Can the LTC3870 model be run on its own?
2. Can you supply an ascii circuit model so I can input parameters?
3. Do you have any reference models for the LTC3870 on its own?
4. Any other suggestions for modelling this device?
