Part Number: UCC2897A Other Parts Discussed in Thread: PMP9656 , PMP3162 , PMP8380 , UCC27511 Hi TI Partner,
After review 3 reference design for 54V to 12V application, I have some questions need confirm with you.
Q1: What is the function of "D8", I see it…
Part Number: PMP3162 Hello team,
Can you please share the complete calculation tool for this design?
This is specifically needed for transformer design.
The part no. PA4141NL comes to be unclassified.
So, would need your support to correctly design the…
Part Number: PMP3162 Other Parts Discussed in Thread: UCC2897A Dear Sir,
Based on the schematics, there are gate drivers on board.(U1/U3/U4)!
Are they necessary?
What is the influence if no use them? Performance?
Thanks.
Part Number: PMP3162 Dear Sir,
I was browsing and i came across PMP3162 design. Im in similar need of such design but it shows it uses are forward transformer PA4141NL. I tried to google it but i cant find any datasheet for that transformer nor i can…
Part Number: PMP3162 Other Parts Discussed in Thread: UCC2897A In another thread, R3 is mentioned as a sense resistor, but I'm unclear as to how it's used here (also new to sense transformers in general). Shouldn't all of the power transformer…
Part Number: UCC2897A Other Parts Discussed in Thread: PMP3162 , , UCC27511 For the UCC2987A reference design (PMP3162), I'm confused about the voltage level seen on the VDD pin (by way of Vbias). The schematic shows a 36-72V input range, and the main…
Part Number: UCC2897A Other Parts Discussed in Thread: UCC27511 , PMP3162 My customer refers to the PMP3162 line, but when it happens to be transient (full load drops to no load), UCC27511 will die (U6 PIN6), how to deal with this problem, Thanks.
Hi Bo,
I would check the VDRV signal to make sure the gate drivers are getting power. The switching of the rectification mosfets are determined by sensing the voltage on the transformer windings. I would compare the waveforms of SEC1, SEC and the output…
Part Number: PMP3162 Hi,
I select PMP3162 reference design to have my own version of 12V/150W and 24V/150W design for our on board power.
I had got TI IC samples of this design, and I design my own customized transformer;
If there are PMP3162 schematic…
