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 725 V MOSFET to reduce the complexity and component count of the design, making it ideal for the increasingly cost-sensitive market for LED-based fluorescent-tube replacements.
The LinkSwitch-PH device performs both PFC and constant-current functions in an advanced single-stage topology, eliminating the need for large, temperature-sensitive electrolytic bulk capacitors, which in turn reduces the size and increases the lifetime of the power supply.
