    Applications

    • Automotive Clusters, Telematics, and Infotainment Systems
    • Camera Modules
    • Key Fobs
    • Industrial Supplies

    Design Notes

    • The step-down topology needs an inductor and output capacitor sized for the ripple at the switching frequency, not just the DC load.
    • Keep the input loop short — high di/dt at the switch node sets conducted EMI.
    • Power switches are integrated, so the thermal path is the PCB copper under the pad.
    • AEC-Q100 qualification suits this part to automotive rails.
    • Package QFN-8 — check the land pattern in the datasheet before layout.
