Sipex is a semiconductor company that designs, builds and markets high performance, high value-added analog integrated circuits. Its products are widely used by original equipment manufacturers (OEMs) engaged in high-growth markets such as the Internet, computers, communications and optical storage.  Power management ICs group includes Low Drop Out linear regulators, DC to DC switching regulators, PWM controllers, charge pumps, and microprocessor supervisors. The serial interface product group contains RS-232, RS-485, high speed, differential transceivers, and dual and multi-protocol transceivers.
The optical storage product family offers complete electronic solutions that enable faster read speeds and smaller footprints in the pick up heads of DVD-R/W, DVD-RAM, and CDRW systems. This family includes photo-detector ICs, laser diode drivers, and advanced power control ICs.

Sipex designs, manufactures and markets high performance, high value-added analog ICs. The products are produced for three fast-growing markets: data communications and communications, battery/portable products, industrial controls/instruments. The company's main product lines include: interface circuits, low-power special application analog ICs and data conversion products. Based on these three products, Sipex's unique positioning is to provide complete analog device solutions to thousands of customers around the world who manufacture wired and wireless data communication hardware, networking and telecommunications equipment, and portable devices. Since 1992, Sipex has released more than 100 varieties of high performance analog ICs. The company is headquartered in Massachusetts, USA, with manufacturing locations and product design centers in California and Massachusetts.

Provides higher power efficiency, lower quiescent current, and longer battery life in a small package. This series includes low-return linear regulators, DC/DC converter regulators, PWM controllers, charge pumps and microprocessor monitors.

Sipex offers the widest selection of serial transceivers. It includes single-protocol integrated circuits supporting RS-232, RS-422 or RS-485, as well as dual-protocol integrated circuits and multi-protocol integrated circuits supporting 2-8 of the most commonly used interface standards.

Optical storage products support faster read speeds, while trajectories are smaller when reading laser heads for systems such as DVD-R/W, DVD-RAM, and CDRW. These products include photodetector integrated circuits, laser diode exciters, and advanced power control ICs.

Sipex is very optimistic about China's development prospects, providing faster, more efficient and more powerful services and technical support to customers in mainland China, Hong Kong and South Asia.
