Shenzhen, China – June 2026

Xuanan Lighting is pleased to announce the release of our new UCS7604‑based addressable LED strip series, featuring 16‑bit (65,536‑level) grayscale, RGBW 4‑in‑1 color control, and break‑point continuation for mission‑critical reliability.

Powered by the UCS7604 driver IC — a 4‑channel, high‑precision constant‑current LED driver — this strip series delivers ultra‑smooth dimming, flicker‑free performance, and vibrant RGBW color mixing. Available in DC5V, DC12V, and DC24V configurations, these strips are ideal for architectural lighting, stage design, retail displays, and high‑end decorative projects.

Why UCS7604? A Technical Overview

The UCS7604 is a professional‑grade LED driver IC with several industry‑leading features:

Feature	Specification
Channels	4 (RGBW)
Grayscale	16‑bit / 65,536 levels per channel
PWM Refresh Rate	16 kHz
Data Transfer Rate	800 kbps or 1.6 Mbps
Output Current per Channel	0 – 60 mA (adjustable)
Port Withstand Voltage	Up to 30V
Redundant Data Line	Yes (break‑point continuation)
Suitable Camera FPS	Up to 533 fps

Key Features

1. 16‑Bit Grayscale – Ultra‑Smooth Dimming

Unlike standard 8‑bit (256‑level) LED chips, the UCS7604 delivers 65,536 brightness levels per color channel. This results in:

Silky‑smooth dimming curves — no visible step changes
Accurate color reproduction — especially important for RGBW mixing
Professional‑grade transitions — ideal for camera‑captured environments

2. 16 kHz PWM Refresh Rate – Flicker‑Free

With a 16 kHz PWM refresh rate, this strip is suitable for high‑speed video recording — supporting camera frame rates up to 533 fps. No flicker, no scanning lines, even under slow‑motion capture.

3. Break‑Point Continuation – Redundant Data Line

The UCS7604 features a dual‑signal input (main data + redundant data). If a single pixel fails, the signal automatically bypasses the fault and continues down the line.

4. RGBW 4‑in‑1 Color – Pure White & Vivid Colors

The 5050 RGBW 4‑in‑1 LED package integrates red, green, blue, and a dedicated white chip in a single housing. This delivers:

Pure, clean white light — not mixed from RGB
More vibrant colors — expanded color gamut
Independent white control — tunable warm/cool white options available

5. Adjustable Output Current – 0–60 mA per Channel

The UCS7604 allows independent current setting for each color channel via an external resistor (REXT). This enables:

Brightness tuning without sacrificing grayscale resolution
Color balance optimization for different LED batches
Flexibility across different PCB copper thicknesses (2oz/3oz/4oz)

Product Line Overview

Part Number	LED Type	LED Density	IC Density	Voltage	Power	PCB Width	Key Feature
XXA‑60D5050WWA‑UCS7604‑5V	5050 WWA	60 LEDs/m	60 ICs/m	DC5V	14.4W/m	12mm	Single‑point control
XXA‑60D5050RGBW‑UCS7604‑12V	5050 RGBW	60 LEDs/m	60 ICs/m	DC12V	18W/m	12mm	Single‑point control
XXA‑60D5050RGBW‑UCS7604‑24V	5050 RGBW	60 LEDs/m	10 ICs/m	DC24V	18W/m	12mm	1 IC controls 6 LEDs

All models feature: 65,536 grayscale, 16 kHz refresh, break‑point continuation, and 2oz/3oz/4oz copper PCB options. Standard length: 5m per roll.

Technical Comparison: UCS7604 vs UCS2904

Feature	UCS7604	UCS2904
Grayscale	65,536 (16‑bit)	256 (8‑bit)
PWM Refresh	16 kHz	1.8 kHz
Suitable Camera FPS	Up to 533 fps	Standard only
Break‑Point Continuation	Yes (redundant data line)	No
Current Adjustment	0–60 mA per channel	Fixed 17mA
Package	SOP10	SOP8

Key takeaway: UCS7604 is a significant upgrade over UCS2904 — higher grayscale, higher refresh rate, and break‑point continuation for enhanced reliability.
