The DP3367S is a common-anode 16-channel low-breakover PWM constant-current driver chip specially designed for LED displays. The chip supports a maximum of 16-bit grayscale levels. It integrates a high-precision current generation circuit technology, enabling the current error between chips to be controlled within 2.0%. Moreover, it integrates a variety of exclusive technologies for enhancing the display effect of LED displays, which can bring more improvements to the displays.

Refresh rate: 7680Hz

Maximum grayscale: 16-bit

ESD ≥ 8KV

Power supply voltage range: 2.6 - 5.5V

Scanning range: 1 - 64 scans, arbitrarily adjustable

16 constant-current output channels

Supports the mode without external resistors

Constant-current output range: 0.5mA - 25mA

Current error between channels (Vout = 0.45V):

    Typical value: ±1.2%

    Maximum value: ±2%

Current error between chips:

    Typical value: ±1.5%

    Maximum value: ±2.0%

Output channels support low knee-point voltage

High grayscale independent refresh, no black field between frames

High refresh rate at low grayscale: Low grayscale supports 1 - 8 times the display frame rate

Internal frequency multiplication GCLK of 120M, lower EMI
