Part Number: UCC2813-4 Hello Team, Good day! Need your inputs on this. Our customer wants to operate the UCC2813-4 at 70V and 60V VCC as the turn-on and off threshold respectively. Is it possible to do this through a voltage divider configuration at the…
Part Number: UCC2813-4 Tool/software: WEBENCH® Design Tools Hi team,
Could you tell me how to select secondary FET instead of diode? As default, it looks WEBENCH generates only secondary diode(Dsec), we can't select FET.
Thank you for your support…
Part Number: UCC2813-4-Q1 Question from customer:
The data sheet contains the following information:
The typical value for the start-up current is 0.1mA, maximum is 0.23mA.
Does this mean that the controller can be guaranteed to…
Part Number: UCC2813-4-Q1 Other Parts Discussed in Thread: UCC1804 The datasheet for the UCC2813-x-Q1 family shows that the VCC ABS MAX rating is 12V. There is a footnote that states "
In normal operation VCC is powered through a current limiting resistor…
Hi! OK I tried a couple of things.
First, I replaced C13 from 120uF to 200uF; it didn't seem to have any impact.
Next, I removed D5 and R3, and powered the UCC2813 from a benchtop supply (10V, current limited to 50mA). I applied AC and then powered…
For the UCC2813-0, UCC2813-2 & UCC2813-3, Dmax = 100%, for these versions OUT pin Fsw= Fosc.
For the UCC2813-1, UCC2813-4 & UCC2813-5, Dmax = 50%, implemented using an internal toggle flip-flop. So for these versions, Fsw = 0.5 * Fosc.…
Other Parts Discussed in Thread: UCC2813-5 , TLV431 , UCC2813-1 , UCC2813-4 Dear all
I will develop the product using UCC2813-5. (Input : AC 50V or DC 50V +/- 30% OutPut : 5V / 12A (60W) A circuit diagram based on the circuit proposed by TI Webench has been…
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…
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 18.104.22.168, Voltage Feedback Compensation, on page 25 of the datasheet…
Here are some part numbers that appeared when I searched for your requirements. I recommend starting to look at UCC28600-Q1.
