Part Number: LM5069EVAL Other Parts Discussed in Thread: LM5069 Hi team,
We are testing LM5069EVAL over current conditio but the action is not aligned with the pricinple as datasheet, pls help to check if it is normal:
Within the fault timeout period…
Part Number: LM5069EVAL Other Parts Discussed in Thread: LM5069 I'd like to ask some questions about the operation of LM5069EVAL(LM5069MMX-2/NOPB). We are currently using the evaluation board "LM5069EVAL" to verify the basic operation for product adoption…
Part Number: LM5069 Hi,
I have some issues with the LM5069 at 54 V while the circuit is working at 24 V. Can you help me ?
Here is the goal application:
First, I would to test the LM5069 with lower load power.
Here is the calculator fulfilled : …
Part Number: LM5069EVAL Other Parts Discussed in Thread: LM5066I , LM5069
I am looking for an Efuse for Vi> 80 to 100V (Viabs> = 100V); and CurrentLimit = 20 to 30 A. We have tested this component (LM5066I) but we prefer CurrentLimit to be hardware based…
Part Number: LM5069EVAL Other Parts Discussed in Thread: LM5069 Hi Expert,
We are studying the LM5069 user guide (AN-1522).
It addressed the Q1 Power limit: 45W at beginning.
May we know why the user guide defined this 45W here.
Best regards,
Eric La…
Part Number: LM5069 I am trying to validate the functionality of the LM5069 chip using the evaluation board. I tested the board as is first, and reached the correct cutoff of 2.5A. I need a current limit of 9A, so I switched R5 to 5mOhms, but this resulted…
Part Number: LM5069EVAL Hi,
I have the LM5069EVAL evaluation board and I am using current limit to 10A (+28V).
I have a couple of question:
The insertion delay (in the LM5069EVAL) is 600ms – why? Can I change it to 200ms.
The restart time is 7.7…
Part Number: LM5069 I need to test the operation of an LM5069-1 part. I got the LM5069EVAL/NOPB board and swapped the LM5069-2 part that shipped with the board for an LM5069-1 part that was ordered at the same time. It needs to switch on at about 18.5V…
Other Parts Discussed in Thread: LM5069 , LM5069EVAL , TPS2493 , LM5060 I have a LM5069EVAL evaluation board that I am using to current limit a large capacitive load during startup (+48V). It takes a significant amount of time to charge the caps to 48V at…
Hi,
This is an interesting test and we will keep this in mind. As we discussed, if the input supply is a current limited power supply, then it will collapse whenever the current goes beyond this limit. This will cause the LM5069 to shutoff by UVLO. Then…
