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…
Yaita,
Here are some part numbers that appeared when I searched for your requirements. I recommend starting to look at UCC28600-Q1.
Part Number
TL2843B-Q1
UC2825A-Q1
UC2856-Q1
UC2856Q
UCC25706-Q1
UCC2813-0-Q1
UCC2813-1-Q1
UCC2813-2…
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…
Other Parts Discussed in Thread: UCC2813-2 , UCC2813-1 Hi,
I have downloaded the ORCAD PSPICE model from TI website & I am getting the below mentioned DRC error message in both the schematics (UCC2813-2 and UCC2813-2).
Please help me to fix this error…
I am suspecting as transition from discontinuous mode to continuous mode may be occurring.
A TPS40210 design will be much better than UCC2813 which needs Vin regulated to below 12V.
PMP7417 and PMP6656 are the best examples of starting…
Hello Emre,
Thank you for uncovering several typographical errors in the application section of our UCC2813-x datasheet. We will begin the process to correct these errors, but this may take many weeks due to internal procedures. Meanwhile, I’ll address…
George,
You are proposing a converter that is at about the upper power limit for what i would recommend for a sepic converter.
As for controllers I expect that any one of our single ended converters would work for your application but since you will…
