Part Number: UC2842 Hi team,
Our customer is now using UC2482 to their fly back power supply and frequency is 60kHz.
But they found that the temperature of UC2482 raise about 50°C in room temperature, and the MOS fly back power supply also rasie too much…
Part Number: UC2842 Hi team,
Good day!
My customer is using UC2842 for their design now, and they confused about the calculation equations of slope compensation in our datasheet. They want to know how are the equation37, equation38 and equation39 derived…

I have designed a 250V @ 0.7A DC DC Push-Pull converter using UC2842 and UC2706. My converter has input of 22V to 35V. I have implemented the design using unitrode refference…
Part Number: UC2842 Other Parts Discussed in Thread: UC2901 , UC2706 , Hi team,
I am designing a DC DC Push-Pull converter with 22V to 34V input range, 280V output with 0.7A Load current. I have selected UC2842 as a PWM controller, UC2706 to convert single…
Part Number: UC2842 Other Parts Discussed in Thread: UC2706 Dear team,
I am designing a push-Pull converter using UC2842 and UC2706 with reference to U-101 200KHz Current-Mode Converter provides 500W.
Can I get the simulation model for the power supply design…
Part Number: UC2842 Hi,
Good Day.
1. What formula to calculate Vbulk (min)? Please provide the formula.
2. "Lm is inductance you chose", so it is 1.8mH or 1.5mH which is Lp. Why don't we say Lp but change the term to Lm?
Please advise.…

Hi,
I am using two UC2842 IC for interleaved boost converter with external clock synchronization at 180 deg phase shift . Below is the connection to make the current reference same for the both the PWM controller.
Please review the…
Part Number: UC2842 Tool/software: WEBENCH® Design Tools Hi,
I generated schematic design. I made a schematic design based on it and PCB too. But İt doesnt work. I study on it since two week. I have two years experience with hardware design. But I dont…

Hi, Ti member
We are developing the buck converter based on UC2842. Instead of current mode, use voltage mode refer datasheet and add additional OPA circuit to limit output current.
there are a…
Part Number: UC2842 Hi E2E,
Good day!
A customer of mine would like to know the purpose of the RT/CT transistor on figure 25 of the UCx84x datasheet.
