Hello,
Please let me know about LM3409HV and TPS92661.
(1) Roff and Coff setting
Could you please let me know the setting method of Coff, Roff for wide Vout range ?
Should we calculate the Coff and Roff by maximum output voltage?
Conditions are the following.
--------
Vin:52V
Vout:about 2V ~ 42V
Iout: 1.1A
--------
(2) LM3409 schematics in the TPS92661 user's guide
There is the LM3409 schematics In the TPA92661-Q1EVM user's guide page 17.
At this schematics , there is the 5V supply for COFF pin.
Could you please let me know the role of this 5V supply ?
Should we add this 5V supply for above consitions ?
Best Regards,
Ryuji Asaka
