The DP3369S is a low-breakover PWM constant-current source driver chip specifically designed for LED displays. The chip supports a maximum of 16-bit grayscale levels. With the high-precision current generation circuit technology integrated inside, the current error between chips can be controlled within 2.0%. Additionally, it incorporates a variety of exclusive technologies to enhance the display effect of LED displays, which can bring more improvements to the displays.

Power supply voltage range: 2.6V - 5.5V

Operating temperature range: -40°C - 85°C

Scanning range: 1 - 64 scans, arbitrarily adjustable

16 constant-current output channels

Supports the mode without external resistors

Constant-current output range:

  0.5mA - 18mA (Vout = 0.3V)

  0.5mA - 25mA (Vout = 0.6V)
