Miray,
The devices are near equivalents.
The UC1843A, and UC2843AN are based on the same silicon design. Differences will include testing, screening, qualification, packaging, and tested temperature range. Electrically they should be similar.
However…
Hey Ron,
I used the schematic under design tools and simulation here: https://www.ti.com/product/UC1843B-SP
I simply added a 0 V source to the TINA reference schematic.
Thanks, Daniel
Part Number: UC1843-SP Other Parts Discussed in Thread: LM139AQML-SP Hi Team, We're almost certain but we need to confirm if the parts UC1843-SP and LM139AQML-SP are non SEL (Single Event Latch-up) sensitive due to their bipolar process. I've also seen…
Hey Juan,
If you are going to use a controller for a buck I would probably suggest using the UC1843B-SP.
The UC1823A-SP likely works better for bucks, but doesn't have the same radiation information the UC1843B-SP has.
As far as how it connects…
Part Number: UC1825B-SP Other Parts Discussed in Thread: UC1843B-SP , Hello,
I am considering the UC1843B-SP for a non-synchronous buck application. The issue I am having trouble resolving is direct duty cycle control through external means. I have…
Part Number: TPS7H5001-SP Other Parts Discussed in Thread: UC1843B-SP , UC1825B-SP Hello,
I am interested in the TPS7H5001-SP but i see that is a prototype/experimental device and is not yet avaible for full production. Is there any components with…
Hello Gg,
The controller works with current mode quite well which accomplishes the benefits of feedforward compensation without dealing with voltage mode. Our online calculator can help calculate the needed components for you for a flyback converter…
Hey Bhavana,
The UC1843B-SP is our suggestion for any singled ended applications (one output)
The UC1825B-SP is our suggestion for applications that need two outputs, but with the outputs 180 degrees out of phase (like a half bridge).
Unfortunately…
Hey Jim,
That size sounds impossible to me, but perhaps you will have better luck than I.
My suggestion would be a non-synchronous flyback using the UC1843B-SP.
Thanks,
Daniel
