Part Number: ATL431 Hi Team,
I want to check the input range of REF pin. This pin range can't be seen in DS. Can you share the detailed information with me?
Thanks,
Gust
I initially suspected capacitors and looked very carefully at that. I inspected carefully for signs of cold solder and found now. I removed the capacitors and inspected to find they were not broken. I reinstalled new good capacitors and found no improvement…
Hi Christian,
It is very unfortunate and I am disappointed that the ATL431 did not work out for you. It is very strange that the ATL431 had a strange behavior that I have not seen before.
Best of luck to you.

Part Number: ATL431 Hello Expert,
I am planning to use ATL431BQDBZR for an SMPS of 5W 20V output and get get confused at designing the value of resistor and capacitor marked in the below figure. Is there any document/article available for the proper design…
Part Number: ATL431 Hi Team,
Example values of Feedback resistor(R1 and R2) are 10kΩ in the data sheet.
1) Is it OK to R1=33kΩ and R2=100kΩ? 2) Do R1 and R2 have upper limit and lower limit? 3) How should we decide which several hundred…
Part Number: ATL431 Other Parts Discussed in Thread: , TL431LI Hi,
I'm considering an ATL431 with Vka=-10V and I'm looking into the stability regions. On Figure16 it looks like the device is stable with 10uF @ 1mA but Figure 20 then seems to imply this…
