characteristic
VK16D32/VK16D33 is a dedicated chip for constant current digital tube or dot matrix LED drive control, which integrates data latch, LED constant current drive module and other circuits. The number of bits scanned can be adjusted through register configuration to obtain a larger single-point drive current.
In the traditional LED display panel driver chip, when the number of lit LEDs changes or the input voltage changes, the current of a single LED will change, which will affect the display brightness; while the VK16D32/VK16D33 adopts a constant current design, when the display mode is configured After completion, the current of each LED is constant and will not fluctuate due to changes in the number of lit LEDs and changes in input voltage.
VK16D32 adopts SSOP24 (150mil-0.635) package; VK16D33 adopts SOP28 (300mil-1.27) package. It is a suitable choice for LED constant current display applications.
