Hello Everyone
I'm trying to build simulation model in LMSpice with the LM2907 but without any success.
my input is 45V@8Khz and I need Vout=0-4.5Vdc
I'm using the LM2907 model (see attached files) for the simulation,
with help from the datasheet, I calculated the following parameters:
C1=1.5nF
R1=25Kohm
I'm not sure what my C2 need to be because it depends on Vripple, so I tried many options,
the biggest problem is the output voltage is always in uV no matter what the C2 will be.
where is my problem?
