LP5811-10 Evaluation Module
Description
The LP5811/10 evaluation module showcases all
the features of the LP5811 and LP5810 4 channels
RGB LED driver with autonomous control. The
difference between the two devices is dependent on
whether there is a synchronous boost function. The
evaluation module includes four ICs on 1 PCB board:
LP5811WCSP, LP5811WSON, LP5810WCSP, and
LP5810WSON. Select the device by jumper setting
and I2C target address. The graphical user interface
(GUI) is called LP581XEVM-GUI. The GUI is used
to interface with USB to the EVM by the USB2ANY
interface adapter.
