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 the…
Hello Navin,
Thanks for your interest in UCC28700, describing your problem, and how you've tried to solve it.
Most flyback controllers from TI should not be limited to applications with DC input voltages above 85 V and/or below 265 V. It's very likely…
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…
