LYTSwitch-6 LED drivers use PowiGaN technology

Power Integrations has announced new high-power-density members of its LYTSwitch-6 family of safety-isolated LED-driver ICs for smart-lighting applications. The new ICs with PowiGaN technology enable designs that deliver up to 110W with 94% conversion efficiency using a simple, flexible flyback topology.

The high efficiency of the new LYTSwitch-6 ICs eliminates the need for heatsinks – greatly reducing ballast size, weight and cooling airflow requirements. The 750 V PowiGaN primary switches provide very low RDS(ON) and reduced switching losses. This improvement, combined with existing LYTSwitch-6 features, increases power conversion efficiency by up to three percent compared to conventional solutions, reducing wasted heat by more than one-third.

LYTSwitch-6 ICs with PowiGaN technology employ lossless current sensing, which contributes to the higher efficiency. The new family members retain existing LYTSwitch-6 benefits such as fast transient response, which facilitates excellent cross regulation for parallel LED strings without the need for additional regulator hardware, and flicker-free system operation. This allows simple implementation of a pulse-width-modulation (PWM) dimming interface.

Comments Hubie Notohamiprodjo, Director of Product Marketing for LED lighting at Power Integrations, said: “The new LYTSwitch-6 ICs with PowiGaN technology enable highly efficient designs up to 110 W for smart residential and commercial fixtures and low-profile ceiling troffers. The high power density of LYTSwitch-6 designs enables reduced height and weight, which is vital for space-constrained and sealed ballast applications.”

The GaN-based LYTSwitch-6 LED-driver ICs are available now, priced at $3.14 in 10,000 quantities.
