The new design is capable of achieving industry-leading efficiency levels of over 90% across a wide input-voltage range while meeting worldwide requirements for power factor and total harmonic distortion, the company said.
The DER-286 LED driver reference design is based on the LNK419EG, a member of Power Integrations’ LinkSwitch-PH family of ICs.
LinkSwitch-PH devices combine a controller and 725V MOSFET to dramatically reduce the complexity and component count of the design, making it ideal for the increasingly cost-sensitive market for LED-based fluorescent-tube replacements.
Power Integrations product marketing manager Andrew Smith said many end users prefer the convenience of a single inventory item that can support installations operating from the US residential supply of 90 VAC to 120 VAC and also the high nominal voltage 277 VAC services of industrial applications.
