MP4470/4470A High-Efficiency, Fast-Transient, 5A, 36V Synchronous, Step-Down Converter DESCRIPTION FEATURES The MP4470/4470A is a fully-integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter. It offers a very compact solution to achieve a 5A, continuous-output current over a wide input-supply range with excellent load and line regulation. It also provides fast transient response and good stability for wide input-supply and load range. The MP4470/4470A operates at high efficiency over a wide output current load range.    MP4470 has full protection features include SCP, OCP, OVP latch, UVP, and thermal shutdown. MP4470A has the same protection features to MP4470 except has no OVP latch function. The MP4470/4470A requires a minimal number of readily-available, standard, external components, and is available in a space-saving 3mm×4mm, 20-pin, QFN package.         Wide 4.5V-to-36V Operating Input Range Guaranteed 5A, Continuous Output Current Internal 40mΩ High-Side, 20mΩ Low-Side Power MOSFETs Proprietary Switching-Loss-Reduction Technology 1% Reference Voltage Programmable Soft-Start Time Low Drop-out Mode 200kHz-to-1MHz Switching Frequency SCP, OCP, OVP Latch(MP4470 only), UVP, and Thermal Shutdown Output Adjustable from 0.8V to 0.9×VIN Available in a 3×4mm 20-pin QFN Package APPLICATIONS       Notebook Systems and I/O Power Automotive Systems Networking Systems Industrial Supplies Optical Communications Systems Distributed Power and POL Systems All MPS parts are lead-free and adhere to the RoHS directive.

The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD(MAX)=(TJ(MAX)TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB.
