I want to use the LM60430A-Q1 part but I see that I need to use the LMR33630, as that part is in the simulation program.

My big problem is that the web-bench program does not give me values for L nor values for the EMI filter that…

Hello,

I noticed that WEBENCH only supports the WSON package for the inverting buck boost configuration.  We have the SOIC package and WEBENCH does not let us create our intended design with it.  We want to understand if there is a…

Hi Team,

There is a good new that we could DIN LMR33630-Q1!

I saw many of LMR33630 EVMs on the official website!
Which one should I apply for LMR33630-Q1 EVM, thank you !

LMR33630ADDA…

 Which are the current limits of this regulators:

LMR33610

LMR33620

LMR33630

LMR33640

And why do they not correspond to the publicized limits of the parts. I mean 1 A…

Hi all,

I have designed power supply using LMR36520, but due to unavailability i have chosen LMR33620 which is pin compatible. I have assembled 5 boards with…

Hello, can you tell me analogue IC of that converter. I need to replace it in a device. 

Hi,

I'd like to ask about minimum off time specs on D/S.

Why does  LMR33630 have different minimum off time depending on package?

Where does this difference come from？ parasitic capacitance or something?

Thanks,

Go

Hi Sirs,

My customer is developing a board to use the LMR33630 for 5Vin to -12Vout and Iout 0.5A.

They found the -Vout pin can not generate the -12V, could you please help to check and advise the schematic?

Thanks for your support…

Hi Team,

Hi Team,

There is a good news that we DIN LMR33630-Q1 !

Please help answer the following questions

1. What will the value of the duty affect LMR33630?
For example, will it affect…

Can the LMR33630 industrial grade be used on automobiles?

What are the main differences between the industrial and automotive classes? In addition to the temperature coefficient and AEC-Q100 certification differences.

What are the…

Hi,

Could you please help with the schematic review?

Thank you!

Best regards,

I'm using LMR36510, but it seems it is out of stock. So I decided to replace it with LMR33620 that I've got from sample.
After I assambled it to my board and turned on the PSU the…

Hi,

I simulate transient result of both LMR33630 and LMR23630 by Webench.  As the result, LMR33630 transient data is better than LMR23630.  Why?   Could you please let us know the reason why…

Hi Sirs,

May I know the LMR33630x all can support generating the negative voltage?

Because I only find the LMR33630A has the simulate tool on the WEBENCH.

The capacitors recommended in the datasheet have a large footprint. Would I be able to use Ceramic Capacitors instead since they have both lower footprint and lower ESR?

Thanks!

Hello, the LMR33630 is not available anywhere that we've seen; can we use the LMR33640 instead?

Thanks,

Derek

Hi,

We tested the device with 16Vin and load of 2.5A. The negative voltage was -4.32V as shown in the screenshot below.

As mentioned in the spec, the negative voltage limit is -3.5V in the spec.We want to know is it ok or is there…

Hi,

I am testing the below circuit  with 24V Power Supply.

My requirement: 3.3V @ 2A..

I have 2 Difficulties as below:

1. With a Load of 2.5Ohm, I am drawing 1.3A yielding 4.4W power. However, the regulator shuts down after 10seconds…

Hello,

I'm using the LMR33630ADDAR, and my system has 2 power sources: a battery and a power supply. When the power supply is connected, a diode switches the input voltage of the LMR33630ADDAR from the battery (5V) to the power supply…

Hi,

We  would like to know the negative voltage limit of LMR33630BRNXT.

We tested the device with 12Vin and load of 2.16A. The negative voltage was -3.84V as shown in the screenshot below.

Thanks,

Shawn

Hello

    I would like to use two for LMR33630-Q1 in parrallel.

One is for 12V to 5V buck, the other is for 12V to 4V buck, are there any pitfalls or potential problems? 

Thanks

1. Please recommend drop in replacement for obsoleted  LM2596T-12/SL110273,  LM2596T-12/S7002179 and LM2596T-12-0135.

2. I cannot find datasheet for these obsoleted regulators. Could you share the datasheet that include these…

Dear Team,

There is good new that we DIN the LMR33630 in customer's new project.

Could you help to review the schematic?

We appreciated your great support!

Many Thanks,

Jimmy

Hi team,

Could you please suggest a p2p device with LMR14030. My customers are using LMR14030 and want a back-up solution.
