    Leveraging the full-chain synergy of its IDM model, crmicro provides customers with high-reliability intelligent LED driver solutions, helping customers develop safe, energy-efficient, and smart vehicle lighting systems.
    Solution Overview
    Targeting the whole-vehicle LED lighting control system, the solution covers the following chain: LED constant-current drive, multi-channel DC-DC power, lamp load switching, and auxiliary voltage regulation. Integrating dedicated automotive lamp driver ICs, multi-channel LED constant-current ICs, three-terminal voltage regulators and SGT/Trench power MOSFETs with comprehensive protection, it delivers stable dimming and load driving for DRLs, tail lamps, etc., optimizing vehicle lighting energy efficiency and overall electrical stability.
    Solution Advantages
    • Fast switching response, precise and fine dimming
    • Stable brightness, no flicker
    • Low conduction loss, low heat generation, strong resistance to vehicle voltage fluctuations and vibrations
    • High lighting reliability, lower energy consumption
    • Fully AEC-Q100 qualified, suitable for automotive applications
