IC LED driver LinkSwitch-PL

dimmable

Description Designed for compact LED replacement lamps, LinkSwitch-PL enables very small and low cost TRIAC dimmable, single-stage, power factor corrected, constant current drivers for solid state lighting. LinkSwitch-PL is optimized for direct LED current sensing, operates over a wide input voltage range and delivers output power up to 16 W. Its innovative control algorithm provides flicker-free TRIAC dimming with minimal external components. Each device incorporates a 725 V rated power MOSFET, a novel discontinuous mode variable frequency/variable on-time controller, frequency jittering, cycle-by-cycle current limit and hysteretic thermal shutdown in a monolithic IC.
