Part Number: UCC3813-5 Hi, we have a product using UCC3813D-5 which convert 7.4V Li-Po input to 500VDC 50mA, but it seems not very stable and very sensitive to the switching transformer in mass production. May I have an TI professional to help review…
Part Number: UCC3813-5 Other Parts Discussed in Thread: UC2845A Hello everyone,
I am using a TI controller for a DCM DC/DC Flyback Converter. I haven't chosen yet between the UCC3813-5 and the UC2845A.
The goal of the DCM DC/DC Flyback Converter…
Other Parts Discussed in Thread: UCC3813-5 , UCC3805 I have been experiencing UCC3813-5 failures in a sepic dc/dc converter so I decided to power the UCC3813 with an 8 volt power supply (through a 250 ohm resistor). The loop was opened so current sense…

Hi support team,
I am looking for a solution that can generate -3000V. PMP2796 with UCC3813-5 generates -150V. Is there any device that can generate -3000V?
Specification…
Hello Jerry,
The attached application note describes the differences between the UCC3800 family and the UCC3813. The UCC3804 is a member of the UCC3800 family of controllers.

Hi,
We do not have a design to match your specs. Also for > 120W, I only find a ref design but not with flyback.

We have an EVM using different topology as well.

Hi Mitchell,
So we typically don't have a negative input to negative output buck converter, and don't recommend you do that with the LMR38025. What you can do is use a PWM controller to do so, as shown here: /cfs-file/__key/communityserver-discussions…
Part Number: PMP11287 Other Parts Discussed in Thread: UCC3813-0 , PMP20708 Hi, Everyone
My customer is requesting the following power supply.
Input:
AC: 10.2 to 126.5V 50/60Hz±5% DC: 10.2 to 126.5V
Output
DC 12V (about 70mA) or DC 5V (about…
Hi Shinichi,
Sorry for the long delay and thanks for already looking at other e2e threads to find an answer.
1. LM5001 is an asynchronous boost converter. It should work for this application, but there are also newer converters with similar specs…
