What the 65V input and 1MHz switching mean for the BOM
The 65V maximum input voltage lets the controller sit directly on 12V, 24V, or 48V automotive buses without a pre-regulator — useful for truck, bus, and off-highway vehicle lighting where the battery rail can spike well above nominal. Because the controller does not integrate internal switches, the external MOSFET and sense resistor selection determines the actual LED current capacity; the controller itself handles the loop compensation and dimming interface.
The 28-TSSOP-EP package with exposed pad helps pull heat into the PCB ground plane.
