Analogue building blocks support AC LED lighting applications

March 18, 2014 // By Paul Buckley
X-FAB Silicon Foundries has a new library of analogue building blocks to help designers create AC LED and AC/DC converter applications quickly and efficiently.

The high-performance power management solutions in 0.18 and 0.35 micron technologies from X-FAB  include the company's ultra-high-voltage CMOS process and a new analogue cell library available in its XU035 process that helps engineers design monolithic AC/DC converters.

X-FAB believes it is the first foundry to offer such a comprehensive targeted analogue library, with 13 new IP blocks including a 5-V linear regulator and voltage reference. Schematic, layout and simulation are available for these IP blocks; silicon proof is expected mid-2014.

The library is based on X-FAB’s cost-optimised XU035 technology – a 0.35 micron modular 700-V ultra-high-voltage non-epi CMOS process with single 5-V gate oxide; it is engineered for applications requiring an integrated power and start-up device solution. The XU035 process offers low specific On-resistance 700V power devices and the lowest mask count in the foundry industry, enabling the most cost-effective solutions for consumer applications. This technology is ideal for energy conservation applications such as AC LED lighting, chargers with no-load power consumption and other power conversion and control applications.
