Part Number: LM5026 Other Parts Discussed in Thread: LM431 Hi All!
I have few questions regarding compensation in LM5026 and would be grateful if you could help explain it.
1. What does this COMP input impedance given in the datasheet refer to and…
Part Number: UCC25660 Other Parts Discussed in Thread: ISOM8110 , LM431 Tool/software: Hi,
When it comes to the UCC256601 LLC controller i need isolated FB , this is normally done through an optocoupler but i noticed that TI has some optoemulators available…
Other Parts Discussed in Thread: LM2904 , LM431 hello?
We use lm2904 to configure and use battery low voltage cutoff circuit.
In some products, the lm2904 output voltage is 0.6V instead of 12V.
The output of the lm2904 is a method of driving the…
Part Number: TL431 Other Parts Discussed in Thread: LM431 Hi Team,
My Customer using this part and find his output voltage ripple will out of spec.
when he operating from half load to full load will see the output ripple will get high then out of…
HI Basil,
We do not. The main difference between the LM431 and LMV431 is the VKA when VREF > 1.24V/2.495V.
For the LM431, When VREF > 2.495V the VKA = ~2V as the app note shows.
For the LMV431, When VREF > 1.24V the VKA = ~1V. This is the main difference…
Hi Neo,
there still seems to be some noise injected into the VREF of the LM431 (Note you mentioned TMV431 several times before but this should be LMV431 -right?)
Would be good to find the route cause of this noise but if not adding a small cap to…
Part Number: TLVH431 Other Parts Discussed in Thread: LMV431 , , LM431 I am doing a bench test comparison of the TLVH431CLPR versus LMV431 voltage shunt devices.
The component test using the circuit below resulted in Vref = 1.24v and Vout = 2.5v as…
Hello Jason,
can you measure the voltage at the Anode of the reference? I am estimating 0.8V+0.35V+2.5V = 3.65V at the ref pin of the LM431.
With a 10k bottom FB resistor the top FB resistor should be 113k.
The device will clamp to around…
Part Number: LM5175 Other Parts Discussed in Thread: INA213 , , LMV431 , LM431 Hi,
I'm facing a very similar design as in https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/561652/lm5175-use-lm5175-with-variable…
