LinkSwitch-II features Power Integrations’ advanced primary-side regulation (PSR) technology, which utilizes a transformer winding to sense the output current rather than relying on lossy, expensive secondary-side components to provide feedback and regulate the output. This cuts system component count by up to 30 percent, resulting in simpler, more reliable and lower-cost designs with extremely good active and standby energy-efficiency performance.
Power Integrations’ PSR technology ensures highly accurate performance, maintaining output current within a +/- 10% range even if load voltage drop, magnetic component tolerance and temperature conditions vary during manufacture or operation. The constant-current drive enabled by LinkSwitch-II ensures that each LED in a series-connected string provides similar light output. This eliminates the current-sharing problem inherent with parallel-connected diodes, and reduces LED binning costs and optical mixing complexity in lighting fixtures.
Unlike many halogen and CFL lights, LED arrays powered by
