MP2492  
2A, 55V, 100kHz Step-Down Converter  
with Programmable Output Current Limit  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
Wide 4.5V to 55V Operating Input Range  
Programmable up to 2A Output Current  
Output Adjustable from 0.8V to 15V  
Programmable Output Current Limit without  
power loss  
The MP2492 is a monolithic step-down switch  
mode converter with a programmable output  
current limit. It achieves 2A continuous output  
current over a wide input supply range with  
excellent load and line regulation.  
0.25Internal Power MOSFET Switch  
Stable with Low ESR Output Ceramic  
Capacitors  
Fixed 100kHz Frequency  
Low EMI signature  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Available in QFN10 and SOIC8E Packages  
The maximum output current can be  
programmed by sensing current through the  
inductor DC resistance (DCR) or an accurate  
sense resistor.  
MP2492 achieves low EMI signature with well  
controlled switching edges.  
Fault condition protection includes cycle-by-cycle  
current limiting, and thermal shutdown.  
APPLICATIONS  
The MP2492 requires a minimum number of  
readily available standard external components.  
The MP2492 is available in QFN10 (3mm x 3mm)  
and SOIC8E packages.  
USB Power Supplies  
Automotive Cigarette Lighter Adapters  
Power Supply for Linear Chargers
