The MPQ4470AGL-AEC1-P is a synchronous step-down DC-DC converter designed for high efficiency and fast transient response, capable of delivering a continuous output current of 5A. It operates over a wide input voltage range of 4.5V to 36V and features internal power MOSFETs with low on-resistance (40m,Ѷ for high-side and 20m,Ѷ for low-side). The device includes comprehensive protection features such as short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown, with the MPQ4470 variant offering latch-off over-voltage protection (OVP). The output voltage is adjustable from 0.8V to 0.9 times the input voltage, and the switching frequency can be set between 100kHz and 1MHz. The MPQ4470AGL-AEC1-P is packaged in a compact 3mm x 4mm QFN format, making it suitable for space-constrained applications. It is rated for AEC-Q100 Grade 1, indicating its suitability for automotive applications. Typical applications include notebook systems, automotive systems, networking systems, and industrial supplies.
