The MPQ4570GF-AEC1-Z is a fully integrated synchronous step-down converter designed to deliver a continuous output current of 3A. It operates within a wide input voltage range of 4.5V to 55V, making it suitable for various applications including industrial power systems, automotive power systems, and Power over Ethernet (PoE) devices. The device features internal high-side and low-side MOSFETs with on-resistances of 90m,Ѷ and 70m,Ѷ, respectively, which contribute to improved efficiency and reduced conduction losses. This regulator employs peak current mode control for output voltage regulation and includes several protective features such as overcurrent protection with valley current detection, overvoltage protection, and thermal shutdown. Additionally, it supports programmable switching frequency and offers an optional external soft start function. The MPQ4570GF-AEC1-Z is packaged in a TSSOP-20 EP format, which includes an exposed pad for enhanced thermal performance. This product is AEC-Q100 qualified, indicating its suitability for automotive applications.
