Featured Products
An 8-channel constant current LED driver offering high accuracy output, advanced error diagnostics, and power-saving features, ideal for applications like traffic signals, VMS, and LED displays.
A 4-channel constant current LED driver with 14-bit APDM control and built-in DMX512 decoding, designed for high-performance, long-distance lighting applications. Ideal for RGB(W) mesh displays and architectural lighting, it supports up to 350 mA per channel, flexible slot-based data loading, and reliable operation across a wide voltage range (7–40 V).
A dual-channel high-side power switch with built-in ghost cancellation, designed to eliminate image artifacts like ghosting and the "worm phenomenon" in dynamic LED displays. With a low 100mΩ on-resistance and up to 2A output current per channel, it ensures clean, reliable performance for both indoor and outdoor LED display applications.
A 3-channel constant current LED driver with 14-bit APDM control and built-in DMX512 decoding, designed for long-distance, high-precision RGB lighting applications. Ideal for mesh displays and architectural lighting.
The MY9758A is a 3×16-channel constant current LED driver with M-PDM technology, enabling high refresh rates and reduced EMI for dynamic LED displays. Ideal for video walls, VMS, and dot matrix modules, it offers precise current control, black frame insertion for blur reduction, and real-time fault detection for reliable, high-quality performance.
