Other Parts Discussed in Thread: UC3825 Hi to everyone,
i am using the uc3825 for a halfbridge converter. i want to know what's the minimum pulse width is?
I am using a switching frequency of 75kHz. Is ther a dependency between the choice of Rt or…
Other Parts Discussed in Thread: UC3825 Hello friends,
I designed 300 W Half-Bridge SMPS with UC3825 IC.
Input Voltage : 230V AC / 325V DC
Output : 30V / 10A
Switching Frequency : 100 kHz
Transformer : ETD39/20/13, Primary : 50 Turns, Secondary1 : 7 Turns…
Other Parts Discussed in Thread: UC3825 I have a problem with PWM modulator UC3825. There are oscillator cycles when there are no drive pulses neither on output A or B. Let see attached diagrams: blue channel is rectified transformer current, yellow and…
Part Number: UCC21520 Other Parts Discussed in Thread: UC3825 , , UCC27324 , UCC27211 , UCC20520 , UCC5350 Hi team,
My customer use UC3825 on secondary side control. the topology is push-pull.
Do you have a suitable isolation solution for driving the primary…
Other Parts Discussed in Thread: UC3825 , UC2825 , UC3825A Hi everybody,
I was reviewing the Power management guide and in the colunm "Typical Power Level" of UC3825 that says 50 to 750W.
Despite this information I guessed that the limitant would…
Other Parts Discussed in Thread: UC3825 Hello Friends,
I designed a 300W SMPS with Push-Pull Topologies. Features: Input Voltage: 220V AC/ 50Hz Output Voltage: 30V/ 10 A PWM IC : UC3825 However, I have a serious problem. Output voltage is normal. I can adjust…
Part Number: UC3825B Other Parts Discussed in Thread: UC3825 Hi,
Good Day. Using the UC3825B for a synchronous buck converter, what do you do with the RAMP and ILIM pins if slope compensation is not used?
Please advise. Thank you very much.
Best Regards…
Other Parts Discussed in Thread: UC3825 Hi all.
There is a question about UC3825.
Is there any example of isolated type ACDC converter application which uses the PHOTO coupler ?
I need sample circuit for UC3825.
Best regards
