LYTSwitch-6 LED Drivers from Power Integrations Use PowiGaN Technology to Deliver Improved Power Density and Efficiency

LDS LYTSwitch driver 400

Oct 15, 2019

Power Integrations 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 110 W 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 3% 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.

    In the lighting industry, the act of “binning” of LEDs is the process of sorting LEDs by certain characteristics, such as colour, voltage, and brightness. The ANSI standard C78.377-2017 provides the dimensions and coordinates of the bins that are currently used to standardize the colour points of all white light LEDs. These dimensions are calculated… Read More…
