Figure 4.17: Backlight Drive Circuit
Note: 1. The backlight circuit should select the chip according to the backlight circuit of LCD. Users should carefully
read the LCD document and select the correct driver chip. The reference circuit provided in this document is a series-
type PWM dimming backlight driver circuit; if a series-type one-line dimming backlight driver circuit (such as
KTD2801) is used due to design requirements, GPIO is required for control.

The SLM756 module supports the MIPI interface Camera and provides a dedicated camera power supply. The main
camera is a CSI0 interface that supports two sets of data lines and can support 8M pixels. The front camera is a CSI1
interface that supports a set of data lines and can support 5M pixels. The module provides the power required by
the Camera, including AVDD-2.85V, IOVDD-1.8V, DVDD-1.2V and AFVDD-2.8V (powering the focus motor).
