Panasonic Electric Works LYTSwitch-6 series LED driver ICs

Power Integrations LYTSwitch™-6 safety-isolated LED driver ICs deliver flicker-free output up to 65 W, and feature up to 94% efficiency with as little as 15 mW standby power. Targeting smart residential and commercial fixtures and low-profile ceiling troffers, LYTSwitch-6 ICs also exhibit fast transient response and allow easy implementation of a pulse-width-modulation (PWM) dimming interface.
