Hello team,
I designed as the following voltage using LM27761
Vin = 5.0V, Vout = -5.0V
So I found the following noise which is more than switching noize. This noize level is almost 70mV.
If I set the Vin voltage is 5.1V, so this noise disappears. So I am thinking that Vin voltage should be increased than 5.1V.
My question is the following.
How much shoud I increase at least about Vin Voltage?
Best Regards,
Akihisa Tamazaki
