Hi Brian,
I tried this same setup on another prototype and I was able to get the same start up waveform. So this is an acceptable startup waveform for us. Thank you for your help.
Regards,
Mikha.
Part Number: PMP20199 Hii Expert
The Design of PMP20199 has Output current as 560mA.I need a the current at output as 600mA.
Could you please suggest me that either the component/parameter to be changed or whatever the changes required to obtain the current…
Part Number: PMP20199 Other Parts Discussed in Thread: UCC28700 Hi,
I am using the PMP20199 reference circuit for my project.
In the output voltage measured across TP3 and TP4 there is a ripple of about 12V. It ranges from 57V to 45V. Also at the Secondary2…
Part Number: PMP20199 Other Parts Discussed in Thread: UCC28700 Hi Expert,
I have implemented a 54V 30W power supply using the UCC28700. The supply has another secondary winding for 4V output. When observing the start up both the outputs, the 54V output…
Hello Downey,
This design is 24V. Major changes would be needed to convert it to 48V, such as transformer change, checking for voltage for everything on the output side. Note: that most of the things on the 24V bus can't support 55V. The current range…
Part Number: TPS23861 Other Parts Discussed in Thread: PMP20199 , TPS2378EVM-105 Dear TI,
I made the board by referring to PMP20199 data.
Is there a way to operate without PD connected to measure EMI?
The reason for this is to see the pure EMI characteristics…
