The MP4470GL-Z is a high-efficiency synchronous step-down converter designed to deliver a continuous output current of 5A with an input voltage range of 4.5V to 36V. It features internal power MOSFETs with low on-resistance, specifically 40mOc for the high-side and 20mOc for the low-side, which contribute to its efficiency and thermal performance. The device supports an adjustable output voltage from 0.8V to 0.9 times the input voltage and operates at a programmable switching frequency between 200kHz and 1MHz. Protection features include short-circuit protection (SCP), over-current protection (OCP), over-voltage protection (OVP) with latching capability, under-voltage protection (UVP), and thermal shutdown, ensuring reliable operation under various conditions. The MP4470GL-Z is packaged in a compact 3mm x 4mm QFN-20 package, making it suitable for space-constrained applications. Typical applications include notebook systems, automotive systems, networking systems, and industrial supplies.
