LM5085MYX/NOPB +BOM

4.5-75V Wide Vin, Constant On-Time Non-Synchronous PFET Buck Controller

LM5085MYX/NOPB Allgemeine Beschreibung

Featuring a nearly constant operating frequency despite line and load variations, the LM5085MYX/NOPB product leverages the inverse relationship between input voltage and on-time. This PFET architecture allows for 100% duty cycle operation and minimal dropout voltage, enhancing overall efficiency. Moreover, the controller supports over-current detection using either the PFET's RDS(ON) or an external sense resistor, further enhancing system reliability and safety
