Part Number: PMP40144 Tool/software: We plan to have a battey backup system when entering low power mode. Under this situation, the Vin will be 12V. We know the range is 36~57V for this design but we want to know how to support the 12V Vin?
Thanks…
Part Number: LM5023 Other Parts Discussed in Thread: UCC28704 , UCC28750 , PMP20771 , PMP40144 , PMP30720 We are looking into low-cost high efficiency Isolated / AC to DC / DC to DC converter for 18-40V AC/DC input to 5V @ 1.5A current. Kindly suggested…
Part Number: UCC28700 Other Parts Discussed in Thread: PMP40144 , UCC28704 Hello,
I want to use this IC to generate 12V from a 48V DC supply. But on the WEBENCH I am not able to give 48V in the input range. Is this IC limited to 85 ≤ value ≤ 265 input…
Part Number: UCC28704 Other Parts Discussed in Thread: PMP40144 Hi
I try to build a DC-DC isolated Buffer in flyback topology with no opto feedback.So I selected the UCC28704.
I have build the circuit similar to the schematic of the PMP40144 but with…

We do not have a reference design with UCC28740 with such a low input voltage nor do we recommend it be used with such a low voltage. UCC28740 is designed for offline AC/DC supplies where the input voltage is typically 85-265 VAC. It includes features…
