Part Number: LMZ14202H We are using the LMZ14202H in many automotive applications for many years.
Recently we found that there is a very high inrush current spike of approx. 11A with a duration of 100mS at startup.
This is with Vin 28V and it is not changing…
Part Number: LMZ14202H I have a similar issue with the LMZ14202HTZ part on two of our boards. What we are experiencing is that the part gets damaged when it goes through the baking process. We have not changed the design for a long time and just this…
Part Number: LMZ14202H Hi experts
I'm working on a new design with this device, and want to minimize the current flowing through the ENable resistor divider network.
Can you provide information on the structure of the input pull-up described in datasheet…
Part Number: LMZ14202H Other Parts Discussed in Thread: LMZ14203H Hello,
we are using LMZ14202H and 14203H since 2014. Most of them being LMZ14202H or the equivalent part from Würth Elektronik (part no.WPMDH115402 - they told us that these are re-labeled…
Part Number: LMZ14202H Hello,
My customer wants to use the LMZ14202H under the following conditions.
- VIN = 28V, VOUT=26.5V , IOUT=1.5A
1. When they run WEBENCH® Designer under the above conditions, an error occurs.
What is the required input…
Part Number: LMZ14202H Hello guys,
I am using LMZ14202H as a BUC Regulator in my application.
1. Input 42V to generate 28V @ 1A - This has power dissipation of 1.8W
2. Input 42V to generate 5V @ 1.2A - This has power dissipation of 1.3W.
My query is …
Part Number: LMZ14202H Other Parts Discussed in Thread: LMZ14203H , LMZ14201H We are using the LMZ1420xH in many of our products.
We are experiencing unprecedented failure rate with the recently purchased LMZ14202H LOT 1520 packed in 5/2021.
We are using…
Part Number: LMZ14202H
HI there,
I designed dc to dc buck converting system by LMZ14202H.
In the LMZ14202H datasheet, there are thermal derating verse output current (stating point is 2A) graphs.
The output current in the data begins to decrease by…
Part Number: LMZ14202H Hi there.
In general, what are some pre-existing symptoms before the end of the converter's life? For example, is a constant drop in output also considered the common foreshadowing? Thank you
Part Number: LMZ14202H Other Parts Discussed in Thread: LMR33620 , LMR36520 , , LMZ14202 HI,
I designed 26.5 V output from 28 V Input by LMZ14202HTZ.
Most samples worked normally, but some samples failed to generate 26.5 voltages.
This happens as the temperature…
