MP1601 1A, Synchronous, Step-Down Converter with 11µA Quiescent Current in SOT563 The Future of Analog IC Technology DESCRIPTION FEATURES The MP1601 is a monolithic, step-down, switchmode 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 MP1601 is available in an ultra-small SOT563 package and requires a minimal number of readily available, standard, external components. The MP1601 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 Power Good Only for Fixed Output Version Wide 2.3V-to-5.5V Operating Input Range Output Adjustable from 0.6V Up to 1A of Output Current 160mΩ and 120mΩ Internal Power MOSFET Switches Output Discharging Short-Circuit Protection (SCP) with Hiccup Mode Stable with Low ESR Output Ceramic Capacitors 100% Duty Cycle 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.
