MP2143  
3A, 5.5V, 1.2MHz, 40μA IQ, COT  
Synchronous Step Down Switcher  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2143 is a monolithic, step-down, switch-  
mode 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.  
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  
Constant-on-time control provides fast transient  
response and eases loop stabilization. Fault-  
condition protections include cycle-by-cycle  
current limiting and thermal shutdown.  
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  
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.  
Available in a TSOT23-8 Package  
APPLICATIONS  
Low Voltage I/O System Power  
Handheld/Battery-powered Systems  
Wireless/Networking Cards  
All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
