Hi Zbynek,
Not sure how much current you need for each LED, if LP5521 is okay for you, you can also check out LP55231, this is very similar to LP5521, but it can drive 9 LEDs, 6 of them is power by the charge pump and 3 of them is power by Vin.

Hi Matt,
Is there a reason why TLC5940 is not an option now?
For most backlight drivers, you can control the brightness level for all, but not individually. For indicator driver, you can control individually, but typically it only supports 1 LED…

Hi Wangjian,
It is ture, you can use the default blinking.
Or you can try the engine control device. LP5562,LP5523,LP55231.
You just the upload the program to the device with the desired pattern, then sleep the MCU.
The device can generate the complicatied…
Part Number: CC2640 Other Parts Discussed in Thread: LP55231 Tool/software: Code Composer Studio Dear Sir,
I am using SensorTag code to modify it to fit my board. I face a problem when I am using I2C to control LP55231 LED driver. I am using the SensorI2C_writeReg…
Hi Johannes,
The datasheet just inform the before version not the first version time.
This device is still available but we didn't know when is the last buy since it depends on the customer order. But we would like recommend the customer to use the…
By the way, we also have a LED Driver (LP55231) connected in the same I2C bus, so we try to write to this peripheral too (slave dir 0x35, we think), but with the same error result.
Best regards.

Hi Natallia,
Not that I know of the is not any application notes on RGB vs RGBW drivers. Now here I am speaking of the LP5523 type family of products. So similar to it there are LP5521, LP5562, LP55231, LP8501. These ones you can use with RGB LEDs as…
Hello,
Could I have the software for LP5523-EVM ?
I can't find the software for LP5523-EVM...
I found the LP55231-EVM software in the below address.
I would like to get the similar file for LM5523-EVM.
