MP2192  
DESCRIPTION  
FEATURES  
The MP2192 is a monolithic, step-down switch-  
mode converter with built-in internal power  
MOSFETs. The MP2192 achieves 2A of  
continuous output current from a 2.5V to 5.5V  
input voltage, with excellent load and line  
regulation. The output voltage can be regulated  
to as low as 0.6V.  
Low 25μA IQ  
1.1MHz Switching Frequency  
EN for Power Sequencing  
1% FB Accuracy  
Wide 2.5V to 5.5V Operating Input Range  
Output Adjustable from 0.6V  
Up to 2A Output Current  
75mΩ and 45mΩ Internal Power MOSFET  
Switches  
Constant-on-time (COT) control provides fast  
transient response and eases loop stabilization.  
Fault protections include cycle-by-cycle current  
limiting and thermal shutdown.  
100% Duty Cycle  
Output Discharge  
VOUT Over-Voltage Protection (OVP)  
Short-Circuit Protection (SCP) with Hiccup  
Mode  
Available in a WLCSP-6 (0.85mmx1.25mm)  
Package  
The MP2192 is well-suited for a wide range of  
applications, including high-performance DSPs,  
wireless power, portable and mobile devices,  
and other low-power systems.  
The MP2192 requires a minimal number of  
Excellent Transient Response with Minimal  
Output Capacitors  
readily

external  
components. It is available in an ultra-small  
CSP-6 (0.85mmx1.25mm) package.  
Optimized Performance with  
MPS Inductor MPL-AL4020 Series  
APPLICATIONS  
Solid State Drives (SSDs)  
Portable Instruments  
Battery-Powered Devices  
Multi-Function Printers
