LED Driver ICs


Power Integrations (San Jose, CA) has added seven LED driver ICs to its LinkSwitch-PH line. The ICs (LNK413-LNK419) are suitable for lighting applications ranging from 3W bulbs to 55W fluorescent lighting fixture replacements. The devices, which can achieve up to 88% efficiency, feature a PWM-dimmable single-stage controller with both power factor correction (PFC) and accurate constant current (CC) power conversion functionality. The integrated PFC and CC functions allow multiple drivers to be connected in parallel. LinkSwitch-PH devices incorporate the PFC/CC controller, a 725V MOSFET, and MOSFET driver into a single package. The new ICs do not include the high-voltage electrolytic bulk capacitor and the optocoupler, components most likely to limit the lifetime of an LED lamp.
