Product Attributes

Introduction

SK9822 is an LED light source control product that integrates a dual-wire transmission channel, three-channel (RGB) driver intelligent control circuit, and light-emitting circuit into a single unit. The product incorporates a signal decoding module, data buffer, built-in constant current circuit, and RC oscillator. Fabricated using CMOS process technology, it features low-voltage and low-power consumption characteristics. It supports 256-level grayscale PWM adjustment and 32-level brightness adjustment. With dual-wire output, the data and synchronized CLK signals enable series synchronization of output actions across each die.

Features

• Integrated high-quality external-control serial cascade constant-current IC; operating voltage 5V; default power-on illumination
• Control circuit and RGB chip integrated in SMD 5050 package, forming a complete pixel control unit with uniform color mixing
• Dual-wire synchronous control
• Three-channel RGB output control, supporting 8-bit (256-level) color and 5-bit (32-level) brightness adjustment
• Three-channel constant-current drive with dedicated signal self-detection
• Serial data input up to 30MHz
• Dual data transmission with built-in uninterrupted oscillation PWM output for static image retention

Applications

• Full-color LED light strings
• Full-color LED modules
• LED rigid light bars and flexible light strips
• LED guardrail tubes
• LED architectural/landscape lighting
