  • RE: TPS62150: Power management forum

    Resolved
    Hi Jack, For TPS62150, I am not familiar with SCR-crowbar circuit and not sure about DC/DC converter behavior. Cycle by cycle current limit is simple. The high-side and low-side FET will resume to normal operation if the over-load is gone. If you need…
