Why PowerMOS
From our first shift-register chip, the D705, in 2007, what PowerMOS has accumulated in PLC pixel-control driving is more than a catalog of parts — it's four generations of complete system capability: chip, protocol, production process and control system, none of them optional.
01 · Innovation
Since shipping our first shift-register chip in 2007, PowerMOS has accumulated end-to-end experience in control systems, graphics production and string manufacturing, building a sustained capacity to independently develop innovative protocols and system conversions.
The first generation validated string-production process and market acceptance, and produced the improvement ideas that shaped the second generation.
Introduced the metal-fuse + poly-fuse address modes and camera-addressing technology, paving the way for automated production.
The first to solve — and volume-produce — in-line address writing on automated string-assembly machines. This was the watershed that moved the industry from manual bead sorting to automated addressing.
Reliability hardening and product-line expansion advanced in parallel: four-channel RGBW output, fixed-code series and parallel-application series were validated and launched in turn, making PowerMOS the supplier with the broadest coverage and the leading quality stability in the field.
The low-level timing decode used for years is limited by wire parasitics that cap refresh rate and total bead count. A next-generation edge-measurement protocol and address-free control scheme have reached engineering samples and are in application validation — with the goal of locking in a technology lead for the next five years.
02 · Integration
Traditional small driver-IC design houses focus on hardware and outsource control-system development, making it hard to meet customers' custom needs quickly. Since 2008, PowerMOS has invested in developing its own master controllers and host-software editing systems in-house — making it the only integrated solution supplier that develops the entire chain — chip architecture, protocol, production addressing and driver control system — in-house among comparable products on the market today.
PowerMOS filed US and EU patents in parallel from the very start of its PLC product line: our own camera-addressing and in-line bead-replacement patents, plus multiple formally licensed key PLC patents — from controller methods and address-burning to bead structure — form tight protection from principle to physical product.

By holding firm on bead-production requirements and a rigorous QC process, we keep the outgoing bead defect rate around 200 PPM; a steady track record of 100M+ cumulative shipments is the most important calling card PowerMOS has.
Whether you're a lighting manufacturer, a brand or an installer, we'd love to talk about how to build a shared advantage in your market.
