Renesas Electronics iW380 High-Resolution Buck LED Drivers feature accurate DC dimming technology, enabling high-performance dimmable commercial lighting systems. These drivers work as stand-alone DC/DC converters or second-stage converters in an AC/DC lighting system. The iW380 high-resolution buck LED drivers accept PWM dimming inputs and analog (DC) to provide an exceptional dimming range. This dimming is offered with an integrated light-off mode ranging from 0.0625% to 100% in 0.0625% steps. The iW380 high-resolution buck LED drivers also work with resistors by dimming the input, offering 3-in-1 dimmer compatibility. These drivers support non-isolated buck converter topology by eliminating virtually all flicker in the system down to 1% and minimizing the low-frequency output ripple current.
