Part Number: LMZ14201 Other Parts Discussed in Thread: , LMZ14203 Tool/software: I'm looking at implementing the LMZ14201 or the LMZ14201H in an inverting (negative voltage) configuration and after looking at (AN-2027 Inverting Application for the…
Hi Andrew,
I received the report from Texas and they confirmed it's a known issue. This is what the report says:
"The non-conforming behavior of the Customer Returned Device (CRD) has been attributed to a known fail mode previously identified for…
Hello,
Since we have not heard back in a while, I am going to close this thread. If you have more questions, you can reply to this thread or open a new one.

Hello,
I have used WEBENCH to generate a -3.3V power supply.
The datasheet of LMZ14201 specifies the minimum voltage 5V.
The topology used is Inverting Buck…
Part Number: LMZ14201H Other Parts Discussed in Thread: LMZ14201 , , LMR36510 We currently have a design that uses an LMZ14201 to generate -5V.
System changes are driving us to need -12V or -15V instead.
Can we replace the LMZ14201 with an LMZ14201H, and…
Part Number: LMZ14201EVAL Other Parts Discussed in Thread: LMZ14201 Hi,
We are currently designing converter circuit using LMZ14201 IC with Vin=24V, Vout=15V with Max load <1A (IC supports up to 1A max) with startup time being 0.5ms considering Css=4.…
Part Number: LMZ14201 Hi! The package marking of our TI p/n LMZ14201TZ-ADJ/NOPB is the following:
1AAE02G3
LMZ14201
TZ-ADJ
The two last lines are the chip part number. What is the meaning of the first line?

Part Number: LMZ14201 We have a board that uses 24VDC nominal and produces 3.8V. The initial load is very low ~3.3mA.
During initial test used a lab power supply to feed VIN started at 10V and increment. At around 20V the current increases again.
Using…
Part Number: LMZ14201 The datasheet recommends feedback resistors in the range of 1k to 10k. This is quite low compared to typical power devices. What would be the consequence of choosing values above 10k?
