Other Parts Discussed in Thread: UC1842 , LM5020 Previously, I was using UC1842 IC. There is any no problem from it.
I want to use LM5020 integrated, but where should I connect the sync input and shutdown points? I want to use my ORCAD Pspice Project.
Part Number: UC1842 The Figure 10 in Datasheet of UC1842 is wrong (see wrong axis scale). Could you please assist with a correct one?
(i.e. 50, 5, printed in between 30 and 40 (3 and 4), resistors started at 3k in diagramm, strictly recommended not under…

Part Number: UC2842 Other Parts Discussed in Thread: UC1842 Why UC1842/2842/3842 have different operating temperature with same pacakge/thermal resistor/Tj=150?
Is it the process difference and what else? Are their die-size different?

Brian
Other Parts Discussed in Thread: UC2842 , UC1842 Hi all
Would you mind if we ask UC1842/3/4/5 and UC2842/3/4/5? We recognize that the formula of minimum on time is as the follow; -tONmin=D / Fsw
About Fsw, there is only typ value. Our customer would like…
Other Parts Discussed in Thread: UC2842 , UC1842 , TPS40210 Hi all Would you mind if we ask UC1842/3/4/5 and UC2842/3/4/5? How much is tON(min) Minimum pulse duration? Of course, we recognize that the minimum duty is 0%(Dmin). As our recgnition, it is possible to…
Part Number: UC2825A-EP Other Parts Discussed in Thread: UC1842 , Hello,
Can you confirm that the UC2825A-EP and the UC1842(3,4,5)A-EP do not have thermal shutdown?
Also, do we have estimated life vs ambient temperature curves for these 2 devices?
Best…
Part Number: UCC28730-Q1 Other Parts Discussed in Thread: UCC28730 , UC1842 Hi team,
Could we use UCC27830-Q1 as a HV boost controller non-isolated boost controller?
I would like to design 110~200V input and 400~500V output system with boost controller…
Hello Jack,
I was unable to find a similar part where the parameters are tested for operation at 125C. A similar par is the UC1842 . This is characterised at 125C but it is not available in VSSOP. http://www.ti.com/lit/ds/symlink/uc1842.pdf . This is available…
