Part Number: UC1843A-SP Other Parts Discussed in Thread: UC3843 , Tool/software: I noticed using the UC1843A-SP model in SIMetrix that the sawtooth waveform on the RT/CT pin goes from 0V to 2V instead of about 1V to 3V, like the UC3843 model. This doesn…
Part Number: UC1843A-SP Other Parts Discussed in Thread: UC1843A
Hello
I am having an issue with the comp pin in the UC1843A spice model being able to be pulled down to regulate the duty ratio. It is used in the feedback loop with the FB pin to gnd so…
Part Number: UC1843A-SP Other Parts Discussed in Thread: UC1843A Hi,
I am planning to use UC1843A-SP for the flight model in my design. Before using it, I will use UC2843AN or UC2843N for the prototype instead of UC1843A-SP. I didn't see detailed information…
Part Number: UC1843A-SP For the HKU pkg (5962P8670409VYC), I see that the lid is metallic and connected to the thermal pad. Is the thermal pad internally connected to GND?
Part Number: UC1843A-SP Other Parts Discussed in Thread: UC1844A ,
Hi,
I'm planning to drive my FET with 300kHz switching frequency and %50 max. duty cycle. Therefore, I'll try to set the internal oscillator to 600kHz.
However, when I arrange it…
Part Number: UC1843A-SP Other Parts Discussed in Thread: UC1843A , Hi,
I'm trying to find some formula and technical notes about how to design feed-forward compensation network for my dc-dc application.
Please provide me some technical note to do it…
Part Number: UC1843-SP Other Parts Discussed in Thread: UC1843A-SP , UC1843B-SP Tool/software: Hello,
Please tell us what the differences are between the UC1843-SP, UC1843A-SP and UC1843B-SP.
Thank you.

¨Dear TI Teams,
I have tried to install and use PSPICE FOR TI but I'm strunglling simulating a ,simple circuit with the UC1843A-SP PWM controller. The schematics is shown below…
Part Number: UC1843 Tool/software: Dear, Friends.
I want to use a UC1843-SP.
I want to know the differents about UC1843, UC1843A, UC1843B.
What device is possible(package) to purchase for space?
UC1843-SP ( 8-DIP , 20-LCC)

Other Parts Discussed in Thread: UC1843A , TINA-TI Dear TI,
(edit change UC1483A to UC1843A)
I'm trying to run a simple simulation moving from TINA_TI to SPICE FOR TI, for simulatiuon capabilities purposes (Monte carlo and so on). The schematics is as…
