LED Driver IC Performs Temperature Management

January 16, 2009 4:32 am | Product Releases | Comments

Optimizing the LED drive current for best luminosity-over-temperature performance, the LDS8160 solid-state lighting driver (SSLD) includes a novel temperature compensation engine and current regulator. The former monitors the in-situ temperature on each LED and independently optimizes the LED current for best luminosity vs. temperature performance. The latter ensures a low drop out voltage on each LED channel of typically 25 mV across the full operating current range.
