Description
General part information
MP1484 Series
The MP1484 is a monolithic synchronous buck regulator. The device integrates top and bottom 85m? MOSFETS that provide 3A of continuous load current over a wide operating input voltage of 4.75V to 18V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on and in shutdown mode, the supply current drops below 1µA. The MP1484 is PIN compatible to the MP1482 2A/18V/Synchronous Step-Down Converter.3A Continuous Output Current Wide 4.75V to 18V Operating Input Range Integrated 85m? Power MOSFET Switches Output Adjustable from 0.925V to 20V Up to 95% Efficiency Programmable Soft-Start Stable with Low ESR Ceramic Output Capacitors Fixed 340KHz Frequency Cycle-by-Cycle Over Current Protection Input Under Voltage Lockout Thermally Enhanced 8-Pin SOIC Package
