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.
