The LM5085MY/NOPB is a high-efficiency PFET switching regulator controller designed for a wide input voltage range of 4.5V to 75V. It features a constant on-time regulation principle, which eliminates the need for loop compensation, simplifying circuit design. The device supports 100% duty cycle operation, making it suitable for low dropout applications. It offers adjustable output voltage starting from 1.25V and includes an internal soft-start timer to manage inrush current. The LM5085MY/NOPB is equipped with thermal shutdown protection and allows for adjustable current limit settings using either the PFET's R_DS(ON) or an external sense resistor. This product is particularly well-suited for automotive infotainment systems, battery/supercapacitor chargers, and LED drivers. It is available in an 8-pin HVSSOP package and is AEC-Q100 Grade 1 qualified, ensuring reliability in automotive applications with an operating temperature range of -40¬8C to 125¬8C.
