Other Parts Discussed in Thread: PMP6024, , TPS92210
As mentioned previously I have built a prototype based on the reference design PMP6024 and have some issue with the startup circuitry and the consequence is that the MOSFET Q1 overheated. After adjusting the resistor values of R1 and R2 I could lower the heat level on the Q1 and achieved 50VDC on the secondary side. But the system is not working proper. Q1 seems never be turned off and properly because of the Aux winding level on T1 pin 5-7. I have looked in the Tidu958 but could not find any information about this level.
Since I don't use MathCAD and it is not possible to have the related data of T1 and I really need som support. Here are some of my questions
What is the level this winding should be? does it really need to have a load on the output (50VDC) to achieve the correct level on the Aux winding? What is the max voltage and current that it can be on this winding since the VAC in is 100- 240V?
Q1 is replaced with STN1HNK60 can it be any issue ?
Is there any specification/datasheet for the T1 ?
Does it any matter if C17 replace with tantalum capacitor?
Is it possible to have the configuration file of the PMP6024 in PDF, i.e exporting from MathCAD Tool?
Thanks in advance!
