Power Integrations’ LYT6078C for Smart Lighting Applications

Power Integrations has announced a new member of the LYT Switch-6 family of safety-isolated LED drivers for smart lighting applications – the LYT6078C.

POWIThis new LYT Switch-6IC uses Power Integrations’ PowiGa  gallium nitride (GaN) technology to deliver efficiency and performance benefits, demonstrated by the new design example report (DER-920) the company is also announcing today.

Hubie Notohamiprodjo, director of product marketing for LED lighting said: “Power Integrations’ new PowiGaN-based LYTSwitch-6 ICs save lighting manufacturers space and system costs for smart lighting power supplies. The company’s key design goals for our latest design report were high power factor, low harmonic content, high efficiency, and 3-in-1 dimming with zero-to-100% output current. The new LYT6078C driver IC combined with our HiperPFS-4 PFC controller easily met these challenges.”

The PowiGaN-based LYT6078C IC incorporates a 750 V power switch and delivers flicker-free output up to 90 W with other members of the family providing up to 110 W. Including both the PFC stage and the LYTSwitch-6 LED driver, system efficiency exceeds 90%. The performance benefits of the LYT6078C are evident in a new design report (DER-920) detailing a two-stage PFC boost plus isolated flyback on a dimmable LED ballast.

It employs the LYTSwitch-6 LYT6078C IC and Power Integrations’ HiperPFS-4 PFS7624C PFC controller and provides peak efficiency of greater than 91% when driving a 48 V LED string at 1350 mA from a 220 VAC to 277 VAC input. In standby mode, system power consumption is less than 80 mW, which provides engineers with substantial flexibility when designing lighting controls and particularly dim-to-off circuits.
