LONDON – Ikon Semiconductor Ltd. (Dublin, Ireland), a fabless semiconductor company chasing LED lighting opportunities, has said it will show a digital LED controller IC at the upcoming Strategies in Light Conference, taking place in Santa Clara, Calif.
The IKS2053 is an ac-to-dc switch-mode power supply controller IC for LED drivers. It is a single-stage controller IC that is designed to sweep up a number of components into a single IC that could offer a retrofit dimmable feature for LED light bulbs.
The company did not state where it is getting the IC made or what generation of process technology it is using.
The 8-pin SOIC provides universal mains operation at voltages up to 265-V ac and 85 percent conversion efficiency. It offers adaptive quasi-resonant operation and user optimization of power factor correction and output current ripple.
Startup current is typically 20-microamps and protection against over-voltage, over-current and over-temperature is built in.
"Retrofit momentum is high, which presents a substantial market opportunity for Ikon Semiconductor. Added to this, our advanced dim-detect engine enables broad dimmer compatibility – an essential feature in a market saturated with disparate dimmer products," said Conor McAuliffe, Ikon Semiconductor's CEO and co-founder. Ikon was founded in January 2009.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
