Part Number: UC1843-SP Can you please provide the thermal resistance JC for this part? the datasheet suggests there is a junction in this part that is rated to 150C but the rest of the datasheet doesnt list thermal resistance data from the case to junction…
Part Number: UC1843-SP Other Parts Discussed in Thread: TPS7H5001-SP Hello,
I have a question about the UC1843-SP. I am working through the datasheet and using the TINA TI simulation “slum213” for the buck converter 18V to 5V. I looked through…
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…
Part Number: UC1843-SP Other Parts Discussed in Thread: UC1843A , UC1843 Can provide the differences in die construction for 5962-8670402VXA, UC1843AMDREP and the 5962-8670409VPA? I would like to understand if the similarities and differences of the dies…
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: UC1901-SP Other Parts Discussed in Thread: UC1843BEVM-CVAL , UC1901 , UC1843-SP , UC1843 , UC1843B-SP Hello, I am designing a power supply using the UC1901-SP for isolated feedback. In the reference design for the 'UC1843BEVM-CVAL' eval board…
