Part Number: UCC2813-2 Other Parts Discussed in Thread: UCC38C43
With a large output Capacitance, can hiccup current limiting be avoided during start up with the UCC2813 device? Using the UCC38C43 part, it takes approx 12ms to rise from 0V to regulation…
Part Number: UCC2813-2 Hi, I am looking at updating one of our current PSU designs which uses a UCC2813D-2.
I have noticed in the datasheet it states the following regarding the timing resistor.
What is the reason for not using less than 10K and what…
Part Number: UCC2813-2 Hi Experts:
My customer is using the UCC2813-2 for the power design , the turn on threshold is 12.5V, however, the maximum rating of VCC is 12V , so I have two questions:
1) The start up voltage should be above the 12.5V which will…

Part Number: UCC2813-2-Q1 Other Parts Discussed in Thread: UCC2802-Q1 , , UCC2800 Hi Team,
My customer is planning to evaluating our UCC2802-Q1, but it seems UCC2813-2-Q1 is almost same with UCC2802-Q1 from the datasheet. Can someone let me know the difference…
webench_design_1362107_97_760128657.pdf Kartik,
I started from the ucc2813-2 product page here and did the webench design without any issues:
See attached webench report that I got.
I also tried it from the product folder of the UCC2813-2-Q1 and it worked…
Other Parts Discussed in Thread: UCC2813-2-Q1 Hi all Would you mind if we ask UCC2813-2-Q1? How much is the maximum COMP's source current of UCC2813-2-Q1? Is there limitation in case of short(COMP conncets to GND)? Kind regards, Hirotaka Matsumoto

Hi
(1) For the minimum VCC voltage, you need to make the VCC above UVLO_on. For UCC2813-0, the UVLO_on is 7.2 V.
(2) Here are differences for different part number from UCC2813-0 to UCC2813-5. They have different turn on voltage of UVLO.
(3) The maximum…
