DM163 QFP44, 8X3 CH (RGB) Constant Current LED Driver (SMD CMS)

The DM163 is a constant current LED driver IC housed in a QFP44 package. It provides 24 output channels organized into three groups of 8, making it suitable for driving complex RGB LED matrices.

Key Specifications

• 24 constant current output channels (60 mA max per channel)
• 14-bit PWM brightness control (8 + 6 bits) via two data banks
• Adjustable output currents using three external resistors
• Serial interface for loading brightness data
• Integrated shift registers and data latches

The DM163 also offers a versatile secondary function: by connecting the VDDH pin to the VDD pin, each output channel can operate as an inverted digital signal, effectively acting as a PWM controller for other LED drivers.
