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 Buddy,
I am still alive.
I change R5 to 1.27ohm and R20 to 5.1Kohm,
Now, the Vout boot to around 12V, but the transformer is very hot under light load (around 500mA) in short time.
Now the question change to be: What I need to change to make…
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…

ucc2897a spec(p16) 8.3.1.14 VDD:o ne of the references
The capacitance on VREF and VDD should be in a minimum ratio of 1:10.
I want to ask if there is any reason for…
Part Number: UCC2897A Other Parts Discussed in Thread: PMP5123 , PMP3162 Hi Team,
The VIN pin (pin1) of UCC2897A only support minimum 18V in datasheet. I found a reference design PMP5123 that can support VIN form 8V to 36V. I saw there is additional…
Part Number: UCC27517A Other Parts Discussed in Thread: UCC27511 , PMP9656 , , UCC27611 , UCC27511A , PMP7451 , PMP3162 , PMP9720 , UCC27517 , UCC27614 Hi team,
For PMP9656, could we use the UCC27517A to replace the UCC27511?
We saw that UCC27517A…
Hello Ben,
Thank you for reply. I know the PMP3162. However, it may be that FETs are turned on simultaneously. If there is no dead time, the switching frequency cannot be increased. I think that to achieve high-speed response performance, it is necessary…
Hi Hardy,
Please take a look at https://www.ti.com/tool/PMP3162?keyMatch=null&tisearch=tidesigns-power
This reference design seems to match most of your requirements however it doesn't go down to 7Vin. Let me know if this is acceptable or not.
Regards…
