Additional Infomation About Product

MP2305 2A, 23V Synchronous Rectified Step-Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP2305 is a monolithic synchronous buck 2A Output Current regulator. The device integrates 130m Wide 4.75V to 23V Operating Input Range MOSFETS that provide 2A continuous load Integrated 130m Power MOSFET Switches current over a wide operating input voltage of Output Adjustable from 0.923V to 20V 4.75V to 23V. Current mode control provides Up to 93% Efficiency fast transient response and cycle-by-cycle Programmable Soft-Start current limit. Stable with Low ESR Ceramic Output Capacitors An adjustable soft-start prevents inrush current Fixed 340kHz Frequency at turn-on. Shutdown mode drops the supply Cycle-by-Cycle Over Current Protection current to 1A. Input Under Voltage Lockout This device, available in an 8-pin SOIC APPLICATIONS package, provides a very compact system Distributed Power Systems solution with minimal reliance on external Networking Systems components.
