LM3463SQ/NOPB

LM3463动态余量控制器，热控制接口和单个通道调光控制 LM3463 Dynamic Headroom Controller with Thermal Control Interface and Individual Channel Dimming Control

DESCRIPON

The LM3463 is a six channel linear LED driver with Dynamic Headroom Control DHC interface that is

specialized for high power LED lighting applications. The variation of the output current of every output channel in the temperature range of -40°C to 125°C is well controlled to less than ±1%. The output current of every channel is accurately matched to each other with less than ± 1% difference as well.
