LNK417EG [Power Integrations]

LinkSwitch-PH integrates a controller and high-voltage power FET into a single package. It implements single-stage power factor correction and constant current output, eliminating optocouplers and secondary current sensing. Features include flicker-free TRIAC dimming, universal input voltage, >90% efficiency, low standby power (<50 mW), and advanced protection (auto-restart, thermal shutdown, open-circuit detection). The devices use frequency jittering to reduce EMI and come in halogen-free/RoHS compliant eSIP-7C and eSIP-7F packages.
