Part Number: UC2842 Tool/software: Hello everyone,
I'm working with the UC2842 and I'm trying to lower its operating frequency when the input voltage is high.
My approach is to use a hysteresis circuit that turns on a transistor when the input voltage…
Part Number: UC2842 Other Parts Discussed in Thread: UCC28C56EVM-066 Hi dear.
I designed SMPS with UC2842AQD8R. My system should start at 200V.
My start up circuit looks like this. It's now activate at 260V.
How can I make it operate at 200V?…
Part Number: UC2842 Other Parts Discussed in Thread: UC1842 Tool/software: In my project, we require a SMPS with an input voltage range of 120V to 200V DC and an output voltage range of 30V to 50V DC. The application demands an open-loop configuration…
Part Number: UC2842 Tool/software: We are currently using an IC that operates in hiccup mode, causing issues with other equipment. The IC restarts instead of ceasing operation when it should, leading to problems. Are there any PWM controllers in the above…

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…
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…
Part Number: UC2842 Other Parts Discussed in Thread: UC3842 Tool/software: Dear experts，
The flyback power supply input voltage is 24VDC ,Vout=16V and the input capacitor is 9 x 10uF MLCCs in parallel.
When the flyback power supply is loaded with…
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…
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…
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…
