    EV4690GSD-00A Smart Bypass For LED Open Protection Evaluation Board

    The MPS EV4690GSD-00A is an evaluation board built around the MP4690 for bench characterisation of the device in its intended topology.

    The MP4690 is a MOSFET based smart bypass for LED open protection, which provides a current bypass in the case of a single LED fails and becomes an open circuit.

    Applications

    • LEDs where Preventive Maintenance is not Practical
    • LED Headlights
    • LEDs with high Reliability Requirements
    • Crowbar Protection for Open Circuit Conditions

    Design Notes

    • The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
    • Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
    • Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
    • Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
