Part Number: UC1843B-SP Tool/software: Greetings,
The PWM controller 5962R8670412VYC (UC1843BHKU-SP) has two NC pins #5 and #6.
Are these pins floating or are they internally connected to some potential?
Thank you,
Alex
Part Number: UC1843B-SP Tool/software: Dear, Friends.

Part Number: UC1843B-SP Hello,
I will be using UC1843B-SP in current-mode control for an inverting buck-boost. Can you provide guidance on how to calculate the appropriate value for Rramp for slope compensation?
Thank you,

Part Number: UC1843B-SP Hi Experts
For the die version of UC1843B-SP, there are pads 14 and 15 that are both labeled Vcc.
But on the datasheet from page schematic, the connections are shown as Vcc and Vc, which both connect to terminal 7 of the package…
Part Number: UC1843B-SP I am making a boost converter in Orcad, but the Rt/Ct is not Oscillating (only a flat line at 5V). I have 25v VCC, Gnd connected and RT/CT connected exactly like below with R= 1.73k and C= 1200pF. I am measuring at the RT/CT pin…
Part Number: UC1843B-SP Other Parts Discussed in Thread: UC1843-SP I am using the UC1843-SP in an application where the error amplifier reference needs to be variable, so I am wondering what is the best way to override the internal error amplifier but…
Part Number: UC1843B-SP Hi team,
Page 29, Note 6 of the datasheet says that the lid and belly pad are internally connected. I don’t see any guidance (maybe I missed it) for what to connect the belly pad to. Should the belly pad be connected to ground…
