Part Number: LMR33620 Tool/software: Dear Sir,
We are using below part number in one of our project,
while doing simulation at our end we were facing some issues. We are using Ansys software for simulation and use .lib format. Please help us to resolve…
Part Number: LMR33620-Q1 Tool/software: hi expert
i have two questions about "AGND TO PGND" spec:
Q1: whether do the following spec(-0.3v ~0.3v) to show the stable performance of "AGND TO PGND"?
Q2: if some (high frequency)noise or…
Part Number: LMR33620 Tool/software: Hi Sir,
I am using LMR33620ADDA in my design. In Datasheet i find two mechanical diagram DDA0008J and DDA0008B.
In these two which one is the mechanical diagram for this part DDA0008B.
Thanks,
Venkat
Part Number: LMR33620-Q1 Other Parts Discussed in Thread: LMR36502 , LMR36501 Tool/software: Hello,
After configuring a design based on a WEBENCH output to use the LMR33620CQ3RNXTQ1, including all passive component values recommended by WEBENCH, I am seeing…
Part Number: LMR33620-Q1 Hi expert，
Whether LMR33620-Q1 can be used for off-board sensor? Please help evaluate the potential risks from your side.
If not, should tracking LDO be used to provide off-board power supply?

Part Number: LMR33620 Hi.
There are three questions.
1. There are two types of LMR33620 PACKAGE: DDA and RNX. Is DATASHEET 1PAGE Low EMI only valid for RNX PACKAGE?(RNX=LOW EMI, DDA ≠ LOW EMI???)
2. Does the LMR33620 RNX PACKAGE have the same EMI characteristics…
Part Number: LMR33620 Hi,
My customer is doing evaluation with LMR33620 with two similar schematics and PCBs.
For the one w/o EMI filter on input 33620-62850, the current will directly go beyond the current limit of the digital power supply (set up as…
Part Number: LMR33620 Hi team,
I have questions regarding a situation that Vin=0V and EN=3.3V
Does this device need power sequence control?
In current system, EN=3.3V and Vin=0V can be happened. What irregular will be happen in this case?
Regarding the…
Part Number: LMR33620 Other Parts Discussed in Thread: LMR33630 I had this issue on my prototype:
My LMR33620ARNX is switching at 140kHz with SW high 99.5% of the time. So Vout is close to Vin and FB is kept at 3V (when Vin=15V).
This was solved when I…
