UCS7624 LED Strip
The UCS7624 is a 4-channel, 65536-level grayscale LED driver IC. This chip supports intelligent defective pixel resumable data transfer. Its internal circuitry includes an MCU digital interface, a data latch, and a high-voltage driver. The chip allows an external MCU to control the brightness of each channel. It can also operate in cascaded mode for outdoor large-screen applications.
With HPD’s intelligent error signal recognition technology, the chip achieves a channel error recognition rate of over 99%. Its patented dual-decoding engine monitors two channels simultaneously. If a signal issue occurs on any channel, the system performs a real-time switch. The RGBW channels of the UCS7624 provide 65535-level grayscale output.
The chip has individual current adjustment for each channel, a high-precision constant current design, and a 32K refresh frequency. These features enable accurate, rich and vivid colour reproduction. The product has good performance, high stability and reliable operation.
Core Features of UCS7624
- Dual-Channel Resumable Transfer (>99% Rate)
Adopts a dual-signal line design (DIN/FDIN). If a single pixel fails, the signal skips the fault point and switches seamlessly, ensuring no dark sections or data misalignment.
32KHz Refresh Rate & 65536 Grayscale
Supports up to 32KHz port refresh rate, eliminating visible lines under camera shooting. Features 4-channel RGBW output with up to 65536-level grayscale for ultra-smooth color transitions.
5V to 48V Wide Voltage Compatibility
Built-in 5V regulator. By adjusting the external resistor, it natively supports 5V, 12V, 24V, 36V, and 48V power buses, with a 40V port withstand voltage.
Innovative Production Fault Testing
Features real-time short-circuit and soft-fault detection. During factory QA, it dynamically indicates hidden open/short circuits via specific colors (R/G/RG) or flashing, highly improving production yield.

UCS7624 vs. UCS7604
For standard landscape lighting where budget optimization is key, the UCS7604 provides a reliable solution supporting 12V/24V topologies, though its standard refresh rate may show minor rolling lines under professional cameras, and long linear runs will require frequent power injections to combat voltage drop.
In contrast, the flagship UCS7624 is engineered for premium, demanding installations; it natively supports up to 48V high-voltage systems to eliminate line losses and enable ultra-long runs with perfectly uniform brightness, while delivering a studio-grade, completely flicker-free 32KHz PWM refresh rate that guarantees crystal-clear, smooth video capture even during high-definition or slow-motion filming.
While the standard UCS7604 relies on passive break-continue dual-channel backup lines where hidden cold-solder or micro-short faults are hard to detect during factory QC, the flagship UCS7624L integrates an active L-P diagnostic algorithm and HPD recognition that instantly flags assembly defects by automatically mapping trace health to visible color codes during testing (Red for main line only, Green for backup only, and Yellow for both perfect).
