Other Parts Discussed in Thread: TPS23754
Hello,
According to the specification of TPS23754, the operating input range of VC is between 8 ~ 18V.
The design of TPS23754-EVM shows that the turn ratio between the Primary and AUX of flyback transformer is 2:1.2.
How can we make sure that VC can be within 15V if Vin is up to 57V. Is there any formula to calculate the voltage
of VC? Dose it refer to Secondary winding?
