Part Number: UCC3813-3 Tool/software: Hi,
I would like to confirm the maximum power dissipation rating for the PW package version of the UCC3813 family (e.g., UCC3813PWTR-3).
In the datasheet’s “Absolute Maximum Ratings” section, only the N package…
Part Number: UCC3813-3 Hi Support Team.
Power dissipation of PW package was not listed in DS.
There was also a description of N,D package.
Could you please tell me the power dissipation (at TA < 25°C) of the PW package?
Best regards,
Yutaro…
Part Number: UCC3813-3 I am using the UCC3813-3 in a flyback to generate 800 V from 48 V.
If a load of 25 mA is connected to the output voltage the duty cycle is 40 % and the transformer heats up to 50 °C.
If no load is connected the output voltage…

I am FAE, one of the customer in central Japan is trying to use UCC3813-3.
According to dataseet, UCC3813 has 2 different current sense comparators (PWM comparator and overcurrent…
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.

Part Number: UCC3813-1 Other Parts Discussed in Thread: UCD3138 , , UCD3138HSFBEVM-029 I am working with a UCD3138 hard switching full bridge evaluation module (UCD3138HSFBEVM-029). It uses a UCC3813-1 for the 3 housekeeping supply rails. Schematic available…
Part Number: UCC2813-0 Other Parts Discussed in Thread: UCC3813-0 , Dear, Sir.
My customer is considering to replace from UCC3813DTR-0 to UCC2813DTR-0,
also from UCC3813DTR-1 to UCC2813DTR-1.
I tried to read out the datasheet, but following are…
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…
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…
