Power Integrations Expands LinkSwitch®-TN IC Family for Energy Efficient Non-Isolated Power Supplies

September 9, 2004
New LNK302 Addresses Lower Power Home Appliance and Industrial Applications

SAN JOSE, Calif. - September 9, 2004 - Power Integrations (NASDAQ: POWI), an industry leader in high-voltage power conversion integrated circuits and the inventor of EcoSmart® energy efficiency technology, today introduced LNK302, a new member of the company's LinkSwitch-TN family of AC-DC power conversion ICs. Designed as a cost-effective replacement for bulky, energy-wasting capacitive droppers and linear transformers, the LinkSwitch-TN family is ideal for use in home appliance and industrial control applications. The addition of LNK302 broadens the product family's effectiveness at lower power levels, offering a modern switching solution to replace older-technology non-isolated, low current (<80 mA) power supplies.

With as few as 15 low-cost, standard components, a LNK302 solution enables an extremely energy efficient switching power supply in a standard buck or buck-boost configuration with universal input (85 VAC to 265 VAC) and ±10% load regulation. Power Integrations' EcoSmart energy efficiency technology dramatically reduces standby and no-load energy consumption, enabling conformance to all current and proposed worldwide standby and no-load energy efficiency guidelines. The LNK302 is ideally suited for a wide range of applications including personal care and home appliances, electronic utility meters, and industrial controls.

Other integrated high performance features include a 700 V Power MOSFET, an oscillator with simple on/off control, high-voltage start-up, current limit, and hysteretic thermal shutdown circuitry on a single CMOS chip. A 66 kHz switching frequency automatically skips cycles at light load to conserve energy while frequency jittering minimizes EMI filter cost.

The LinkSwitch-TN family is supported by a comprehensive data sheet, application note (AN-37), application circuits, and PI Expert™ power supply design software. All are downloadable from the Power Integrations Web site. A reference design kit (DAK-48A) containing a tested 1.44 W universal input AC-DC power supply, product samples, and support collateral is also available.

Pricing in 1000-piece quantities for the LNK302P, an 80 mA part housed in a plastic DIP-8 package, is $0.49 each. A surface mountable SMD-8 package option is also available. Production quantities are available four weeks ARO. The DAK-48A is available from the company's distributors for $19.95 each.
