Part Number: LM3478Q-Q1 Tool/software: Hi team,
LM3478Q-Q1 has internal soft start control and 4ms typ value in datasheet. But customer found that the soft start time is changing along with VIN. The lower VIN the higher soft start rising time. May I…
Part Number: LM3478Q-Q1 Tool/software: Hi team,
There have some PSPICE model available on ti.com. Would like to check with you if these simulation model can be used in SIMPLIS and SIMETRIX as well?
Thanks!
