PRODUCTION DATA
Figure 10-1 shows an example of typical application, which uses one LP5813 to drive RGB LEDs through I2C communication.
Figure 10-2 shows an example when the boost converter is not need to be used. Directly supply the power the VOUT and pull EN to low can bypass the integrated boost converter and operate the LED driver blocks.
Figure 10-3 shows the connection for 2 pcs LP5813 to drive 8 RGB LEDs (24 LEDs). One LP5813 (Device 0) can work as main part to provide boost voltage for all 8 RGB LEDs, while another LP5813 (Device 1) can work as bypassing boost converter application to save one inductor. If autonomous animation need to be performed, to avoid animation mismatch between two devices in long-time operation, 'vsync_out_en' bit in Dev_Config_11 register of one device need to be set as 1h to provide the same clock to another device.
