Part Number: LMZ20502 Hi Team,
Can you please advise here?
"
As far as I can see, Voltage input range max = 5.5V but we want to supply the module with 5.8V continuously. Will there be a shortening of the module's life?

Thanks in advanc…
Part Number: LMZ20502 Hi Team, do you have an experience that during startup the IC only has 0.6V instead of 2.5V. What are the possible usual rootcause of this situation?
Thank you very much.

Part Number: LMZ20502 Other Parts Discussed in Thread: TPSM82822 Hi team,
It is nice to know you here. My customer used LMZ20502 as below, but the output voltage has a very strange rise edge at start-up. Could you please share with me what may cause this…
Part Number: LMZ20502 Other Parts Discussed in Thread: TPS82084 , TPSM82822 I would like to delay the startup of the LMZ20502, with a wide relative tolerance for timing accuracy (eg 8-12ms is fine with me). While I recognize that EN is not listed as a…
Part Number: LMZ20502 Tool/software: WEBENCH® Design Tools Using Webbench my 5V to 3.3Vdc circuit puts out 4.1V. The resistor values suggested Rfbt= 232K in parallel with 12pf and Rfbb= 51.7K
What causes this error? Is there a minimum load for this part…
Part Number: LMZ20502 Hi Experts:
I'd like to know the response time of the power good?
If there is the overvoltage or undervoltage of the output in the case of the load jumping, how about the behavior of the PG signal , will change accordingly or…
Part Number: LMZ20502 Other Parts Discussed in Thread: TPS82084 , , Dear Sir,
In fact I used TPS82084 in my previous design, it work well .because it cannot be bought in stock recently, I have to use LM20502 instead. but I forgot add Cff in my design. the…
Hi Jimmy,
We had to send the boards out to replace the LMX20502s. We have three boards with the same failures. We replaced the LMZ20502 chips on all three boards, and two are now working and one still fails. We have a few questions that we need your help…
Part Number: LMZ20502 Dear sir or madam
I have a problem with LMZ20502 in my board. The schematic is below.
While , After 3.3V powered up and chip enabled , I could see the 1.8V output from a multimeter in a very short time , and then it turned to 1…
Part Number: LMZ20502 Dear Sir,
I cannot find PCB layout parameters on LMZ20502 datasheet, I use Ultralibrian to convert .bxl to PADS logic/PADS layut style, but I cannot convert .c, .d, .p file to PADS VX1.2 format.
So, can TI provide a detailed PCB…
