MP2361 2A, 23V, 1.4MHz Step-Down Converter The Future of Analog IC Technology FEATURES DESCRIPTION 2A Output Current The MP2361 is a monolithic step-down switch 0.18 Internal Power MOSFET Switch mode converter with a built-in internal power Stable with Low ESR Output Ceramic MOSFET. It achieves 2A continuous output Capacitors current over a wide input supply range with 90% Efficiency excellent load and line regulation. 20 A Shutdown Mode Current mode operation provides fast transient Fixed 1.4MHz Frequency response and eases loop stabilization. Thermal Shutdown Fault condition protections include cycle-by-cycle Cycle-by-Cycle Over Current Protection current limiting and thermal shutdown. In Wide 4.75V to 23V Operating Input Range shutdown mode the regulator draws 20A of Output Adjustable from 0.92V to 16V supply current. Programmable soft-start Programmable Under Voltage Lockout minimizes the inrush supply current and the Available in QFN10, MSOP10, MSOP10E, output overshoot at initial startup. and SOIC8 Packages The MP2361 requires a minimum number of APPLICATIONS readily available standard external components.
