LP5890: 33x22=726 LEDs

Dice-K

Part Number: LP5890

Tool/software:

Hi support team,
I am looking for a device that meets the following specifications.

■Specifications
- 33x22=726 LEDs
- No MCU control
- 50 LEDs light up at once
- Red (2mA), white (2mA) LEDs

Is it optimal to use two LP5890s?
Are there any better devices?

Regards,

Hi Dice-k,

does each LED need to be controlled individually?

Hi Monet,
Thank you for your reply.

They are the same color and brightness at the same time, so I don't think they are individually controlled.

The image below is an example.

Best regards,

Hi Dice-k,

it looks like each LED should be on/off individually, right?

according to your current request, we suggest to use 2 LP5890 to control 726 LEDs.

by the way, the LED is RGB or RW?

Hi Monet,
Thank you for your support.

Yes, ON/OFF is controlled individually.
The LEDs are Red and White.
Is using two LP5890s the best choice?
