You can use pin to pin device UCC28C42-Q1, which has a Tj up to 125C.
Besides, you can also consider these devices such as UC1842, UC1842A,UC1843A, UCCx800, UCCx802, and UCCx803, UCC2813-0/-2/-3-Q,..........Maybe it needs a little circuit mod…
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 not clear…
The UCC2813-2 has an internal clamp that tracks the UVLO turn-on level.
The UCC2813-2 needs to be powered through a series resistor which will limit the current into the Vcc pin and clamp circuit to less than 30mA.
The note 3, section, 7.1…
Part Number: UCC2813-5-Q1 Hi, I try to develop an isolated DC/DC with 9 - 32 V input and 12 V output with 3 A. If I decrease the input voltage under about 20 V, the output voltage is decreasing too. I think the problem is the current sensing of the controller…
UC2813 has the same pin configuration as the UC2842/3/4/5 family. there is a detailed section in the datasheet for finding the voltage feedback loop compensation. The section is 220.127.116.11, Voltage Feedback Compensation, on page 25 of the datasheet…
I just got back in to see if there were any comments added and noticed that schematic I cut and pasted is not showing up. I'm trying again by converting the Webench output to a Word document.

Part Number: UCC2813-1 Hello,
Regarding to Absolute Maximum Ratings on UCC2813-1, my customer is asking some question.
They are understanding that even if Vcc exceeds 12V(Absolute Maximum Ratings), it is no problem when Icc does not exceed 10mA.
Part Number: UCC2813-2-Q1 Other Parts Discussed in Thread: UCC2813-2 , Tool/software: WEBENCH® Design Tools Hello.
We intend to use device UCC2813QDR-2Q1 to design a power supply for our inverter application. UCC2813QDR-2Q1 was suggested to us by the WEBENCH…
Could you inform to me the result of circuit review data ?
Unforturnally, the Power board is not working. so I have some question about UCC2813-5
1. VCC : Test data is 3.8V( UVLO=3.6V)
2. RC : 20Hz~21Hz
3. VREF is PWM signal
If possible, Could…
