Part Number: PMP5726 Hello, seniors:
I want to refer to your PMP5726 case to make a full brick power supply with 48V input and 50V / 20A / 1000W output.
I have preliminarily studied the schematic diagram of your PMP5726, and I have some questions to ask…
Sorry for confusing you, the reference design PMP5726 and PMP7246 shows the Phase shift full bridge can support 2 quadrant application. The output current could be reverse when output voltage is decreasing linearly.
The reference design PMP5726…
Below are some links to applications using UCC272xx drivers.
If you need details on other aspects of driver, then please let me know.
There are a number of possible issues here -
Does the input voltage at the PSFB bridge drop when the load is applied suddenly. If the input voltage drops it could mean that the controller cannot deliver the correct output voltage even if it runs…
There are a couple of conditions to consider here:
First - If diode rectification is used then the DCM function is redundant and the DCM pin can be tied to VREF. This disables the OUTE and OUTF signals for a small reduction in system…
