LP5813: LP5813 only boost? Buck?

Hi Stas,

No, it can't work as buck.

If your battery voltage is more than your output voltage, I'd like to recommend you to use it in pass through mode.

Hi Jared! I have some related questions:

1. Do You plan to improve it to buck-boost in near future? If You plan I leave LP5813 in project for future, now i just bypass boost.

2. If no buck planned I see a mention of LP5812 DSBGA-9 in LP5813 datasheet. I also take a look in your LP5813-12 EVM, where I found LP5812AYBHR. I see it is much easier for layout, because if I don't need SYNC, I don't need complicated vias under BGA, so it makes design cheaper.

3. I don't see LP5813 in the market. I also don't see LP5812 page. Can You give me info about availability of these ICs? I am in design for 2nd version of product, and I am very interested by many reasons to replace my LP5012 to one of these IC. I think product will go from now in 3 month.

I also would like to ask if I can get LP5812 samples.

Hi Stas,

Yes, of course you can. LP5812 is expected to be RTM in these few days. Actually, the RTM signoff request has been submitted. I think you can apply in a few days. If you are very urgent, maybe you can contact me via email and we can provide the LP5812 samples via ZS order. Thanks!

Hi!

Sorry I skipped mail from Your reply, good I come back to check!

I would like to (if possible) to receive LP5812 samples: 10(15) one address and 10(15) different address (there will be 2 on one I2C).

10 is good, 15 will be great!

I will be happy to have it on my table in 2 weeks.

If You agree I will fast prepare Flex PCB to check it.

If You have any information about production start date/volume it will be also good,

because once I check it works, I will need to convince production for ECO changes.

So pricing and availability info is a must for ECO.

You can feel free to contact me
