Zhou,
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.…

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…
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.

Other Parts Discussed in Thread: SG2524 , UC28025 , UCC28950 , UCC2895 Dear All,
I have two questions about IC numbers:
1) what is the meaning of prefixes, ie UCC, UC, SG, TL? ( for example SG2524 or UCC2813 )
2) what is the meaning of digits after prefixes…

I think about the multi-output by flayback. (DC3.3V/450mA, DC15V/10mA, DC-15V/10mA, DC24V/30mA) Our customer made the…
Hello Edward,
Based on this rather limited set of requirements, the tentative answer is YES.
Can you please clarify if the input voltage Vin is AC or DC?
If it is DC, then yes the UCC28740 can readily support that spec since the HV input is rated…
Yaita,
Here are some part numbers that appeared when I searched for your requirements. I recommend starting to look at UCC28600-Q1.

Other Parts Discussed in Thread: UCC2813-1 Hi,
I have designed Multi-output flyback power supply by using UCC2813-1 PWM IC,
Input and output specifications are as follows
Vinput- 16V-40V
Vout-5V@5A,+15V@0.75A,-15V@0.75A
Switching frequency -200kHz
The converter…
Hello Atul,
The question of what is the "best" solution depends on your specific goals. Most often, "best" translates into simplest or cheapest. I suggest that you investigate using one of the UCC2813-x family of low-cost PWM controllers, specifically…
Hello Matsumoto-san,
I'm sorry for the delay in our reply. Mike has been out of the office due to the holidays.
In the UCC2813-x datasheet, page 17, Figure 25 shows the resistance ratio to be 0.65R to 1R, top to bottom.
The actual values are…
