Power Integrations’ isolated LED drivers

19 November 2014 News

The LYTSwitch-2 family of isolated LED drivers from Power Integrations delivers up to 12 Watts of accurately controlled output power and reduces component count for simpler, smaller, more reliable LED lighting designs.

The ICs use primary-side control, resulting in cost-effective, single-sided printed circuit boards with low component counts. In addition, driver isolation allows the LEDs to be affixed directly to a metal heatsink, avoiding the added expense of an electrically isolating enclosure that is often required for non-isolated drivers.

Accurate constant-current (CC) output tolerance across temperature (better than ±5% at both low-line and high-line voltages) reduces the need to over-design systems in order to meet standards requirements. Efficiencies as high as 90% can be expected in typical applications.

LYTSwitch-2 protects the LED load from surges in line voltage, increasing bulb lifetime in regions where the mains voltage is subject to frequent peaks. Its constant-current and constant-voltage (CC/CV) control function maintains a constant voltage on the output of the driver during no-load operation, preventing damage to the output filter or shutting down the driver when being tested or installed with no LED string connected.

The drivers feature over-temperature, over-current and open feedback-loop protection and are simple to design in using Power Integrations’ PI Expert design software. They are packaged in small, cost-efficient SO-8 packages as well as MSOP and eSIP packages for efficient thermal transfer in higher-power applications.
