Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hi,
TI does not have a TINA model for UC1845A. You see in the UC3845 and UC3845A product folders, we offer a UCC28C45 PSPICE model only. I offered you a UCC28C42 TINA model which is close to UCC28C45 but differing only by UVLO level and 100% vs 50% max…

No, LM5021 cannot support such a low input voltage. The abs max UVLO turn on threshold on VIN pin is 23 V, so it cannot be guaranteed that LM5021 will startup with any input voltage lower than this. Alternative devices that can meet your specifications…
Other Parts Discussed in Thread: UCC28C41 , UCC28C45 , UCC38C41 , UCC38C45 hi Team:
I want to designed a Isolate dc-dc power!
Vin: 10-16V
Vout:+12V/1A,-12V/0/5A;
product Size: 30*30*12mm can OK? if not,Product size can be increased;
Do you have any recommendations…

LM5025 and LM5026 can start up and operate when an external voltage between 8V to 15V is applied to VCC, as specified in section 6.3 Recommended Operating Conditions of both datasheets. PMP7895 is an example reference design with LM5026 where…
Hello jayabharath ,
You will find it very difficult to design a power supply with an input voltage that extends down to zero volts.
If your input has a lower limit of about 7V then you should consider using the UCC28C41.
Please check your design requirements…
Part Number: UC2844A Other Parts Discussed in Thread: UCC28C41-Q1 , , UCC28C40 Hi Expert,
Do we have automotive qualified for UC2844A? Our automotive device UCC28C41-Q1 UVLO hysteresis is only 0.6V.
Thanks a lot..

Part Number: UCC28910 Other Parts Discussed in Thread: UCC28C41 Hi-team.
I am promoting UCC28910 for applications of smart meters and electronic breakers.
At that time, could you tell me the following questions?

Other Parts Discussed in Thread: UCC28C43-EP , UCC28C41 , UCC28C44 , UCC28C42 , UCC28C40 Hi,
The datasheet for the UCC28C43-EP list a few other devices that don't seem to be available namley the UCC28C44-EP. Does this device exist? Is there an alternative…
Viktorija,
Thanks for the interest here.
This is an interesting question. I don't think we've tested this before but I don't see why it wouldn't work.
Can you help me understand why this approach is of interest?
Since it's not isolated…
