MIC4801 Overview
The MIC4801 is a high efficiency White LED (WLED) driver designed to drive a single LED up to 600mA. The MIC4801 constant current driver is designed to drive high power LED’s in various lighting applications. The MIC4801 provides the highest possible efficiency as this architecture has no switching losses present in traditional charge pumps or inductive boost circuits.
