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…
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.

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 similar…
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 found…
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,…
Hey Alessandro,
I would personally warn you against using the TPS50601A-SP as an inverting buck-boost.
I have personally tried it in the past and found issues inherent to the device that caused issues with the frequency response as well as drawing too…
Hi,
Unfortunately, it looks like this device would not work for your design. There are a few special considerations that apply when using a Buck in an Inverting Buck-Boost configuration. One major requirement is that the input-to-output differential does…
