DESCRIPTION The MP2143 is a monolithic, step-down, switchmode converter with internal power MOSFETs. It can achieve up to 3A continuous output current from a 2.5V–to-5.5V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.6V. Constant-on-time control provides fast transient response and eases loop stabilization. Faultcondition protections include cycle-by-cycle current limiting and thermal shutdown. The MP2143 is available in small TSOT23-8 package and requires only a minimal number of readily-available standard external components. The MP2143 is ideal for a wide range of applications including high-performance DSPs, FPGAs, smartphones, portable instruments, and DVD drivers. FEATURES Wide 2.5V-to-5.5V Operating Input Range Output Voltage as Low as 0.6V 100% Duty Cycle in Dropout Up to 3A Output Current Low IQ: 40µA 80mΩ and 40mΩ Internal Power MOSFET Switches Default 1.2MHz Switching Frequency EN and Power-Good for Power Sequencing Cycle-by-Cycle Over-Current Protection Auto Discharge at Power Off Short-Circuit Protect with Hiccup Mode Stable with Low-ESR Output Ceramic Capacitors Available in a TSOT23-8 Package APPLICATIONS Low Voltage I/O System Power Handheld/Battery-powered Systems Wireless/Networking Cards
