MP2141NGTF-18-Z

MP2141N 1A, Synchronous, Step-Down Converter with 11µA Quiescent Current in SOT563 DESCRIPTION FEATURES The MP2141N is a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs. It can achieve 1A of continuous output current from a 2.3V-to-5.5V input voltage range with excellent load and line regulation. The output voltage can be regulated as low as 0.6V.        The constant-on-time control scheme provides a fast transient response and eases loop stabilization. Fault protections include cycle-bycycle current limiting and thermal shutdown.   The MP2141N is available in an ultra-small SOT563 package and requires a minimal number of readily available, standard, external components. The MP2141N is ideal for a wide range of applications, including high-performance DSPs, wireless power, portable and mobile devices, and other low-power systems.     Low Quiescent Current: 11μA 2.2MHz Switching Frequency EN for Power Sequencing Wide 2.3V-to-5.5V Operating Input Range Output Adjustable from 0.6V Up to 1A Output Current 120mΩ and 80mΩ Internal Power MOSFET Switches Output Discharge Short-Circuit Protection (SCP) with Hiccup Mode Stable with Low ESR Output Ceramic Capacitors 100% Duty Cycle Power Good Only for Fixed Output Version Available in a SOT563 Package APPLICATIONS     Wireless/Networking Cards Portable and Mobile Devices Battery-Powered Devices Low-Voltage I/O System Power All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
