4-channel constant-current LED driver IC, typically used for RGBW or multi-channel lighting. Uses an external clock and supports daisy-chaining for larger LED arrays.
- Channels: 4 (constant current)
- PWM frequency: 1 or 4 kHz
- Theoretical FPS: Very high (panel driver, not pixel-limited)
- Backup data: No
- Use cases: RGBW fixtures, architectural lighting, LED panels
