MP2158  
1A, 6V, 1.5MHz, 17μA IQ, COT  
Synchronous Step Down Switcher  
In Ultra-small 2x1.5mm QFN  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2158 is a monolithic step-down switch  
mode converter with built-in internal power  
MOSFETs. It achieves 1A continuous output  
current from a 2.5V to 6V input voltage with  
excellent load and line regulation. The output  
voltage can be regulated as low as 0.6V.  
Very Low IQ: 17μA  
Default 1.5MHz Switching Frequency  
EN and Power Good for Power Sequencing  
Ultra-small 2.0x1.5mm QFN8 Package  
Wide 2.5V to 6V Operating Input Range  
Output Adjustable from 0.6V  
Up to 1A Output Current  
118mΩ and 88mΩ Internal Power MOSFET  
Switches  
Cycle-by-Cycle Over Current Protection  
Short Circuit Protect with Hiccup Mode  
Stable with Low ESR Output Ceramic  
Capacitors  
The  
Constant-On-Time  
control  
scheme  
provides fast transient response and eases loop  
stabilization. Fault condition protection includes  
cycle-by-cycle current limiting and thermal  
shutdown.  
The MP2158 is available in the small QFN8  
2.0x1.5mm package and requires a minimum  
number of readily available standard external  
components.  
APPLICATIONS  
Wireless/Networking Cards  
Portable Instruments  
Battery Powered Devices  
Low Voltage I/O System Power  
The MP2158 is ideal for a wide range of  
applications including High Performance DSPs,  
FPGAs, PDAs, and portable instruments.  
All MPS parts are lead-free and adhere to the RoHS directive. For MPS green  
status, please visit MPS website under Products, Quality Assurance page.
