MP4470GL Datasheet | Monolithic Power Systems

DESCRIPTION The MP4470/4470A is a fully-integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter. It offers a very pact 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 ponents, and is available in a space-saving 3mm×4mm, 20-pin, QFN package. TYPICAL APPLICATION FEATURES - 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 - 200k Hz-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 munications Systems - Distributed Power and POL Systems All MPS parts are lead-free and adhere to the Ro HS directive.
