Power Integrations Extends LinkSwitch Family

The new LNK500 from Power Integrations Inc. is a high-voltage monolithic power conversion IC that uses the same primary switching power supply topology as the current LNK501, but takes full advantage of the loose output current characteristic of most low-end linear transformer designs. Its wider output current tolerance of ± 25% allows for lower system cost— most critical barrier in replacing older linear transformer designs. Switcher benefits of a LinkSwitch-based power supply include smaller size, lighter weight, superior performance, and significantly higher energy efficiency.

With as few as 14 components, the LNK500, using the company’s EcoSmart® technology, enables a fault protected, universal input (85Vac to 265Vac), constant voltage (CV) or constant voltage, constant current (CV/CC) output switching power supply that meets worldwide energy efficiency standards.

Applications include linear transformer replacement in adapters and battery chargers for a wide range of personal electronics such as cell phones, cordless phones, PDAs, digital cameras, MP3 players, shavers, home appliances, television standby, and other auxiliary power supplies.
