LED drivers achieve up to 88% efficiency

Members of the LinkSwitch-PH family of LED driver ICs, the LNK413/4/5/6/7/8/9 suit lighting applications ranging from 3-W bulbs to 55-W replacements for fluorescent lighting fixtures. 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 to drive exterior and street area lights efficiently and with functional redundancy. Besides this PFC/CC controller, the parts feature a 725-V MOSFET and MOSFET driver — all into a single package — which simplifies layout and design and eliminates parasitic elements between the controller and MOSFET. They provide a low standby power remote on/off feature. (
