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.
