MP2494  
2A, 55V, 100kHz Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2494 is a monolithic step-down switch  
mode converter. It achieves 2A continuous  
output current over a wide input supply range  
with excellent load and line regulation.  
Wide 4.5V to 55V Operating Input Range  
Output Adjustable from 0.8V to 15V  
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 SOIC8 and SOIC8E packages  
MP2494 achieves low EMI signature with well  
controlled switching edges.  
Fault condition protection includes cycle-by-cycle  
current limiting and thermal shutdown.  
The MP2494 requires a minimum number of  
readily available standard external components.  
The MP2494 is available in SOIC8 and SOIC8E  
package.  
APPLICATIONS  
USB Power Supplies  
Automotive Cigarette Lighter Adapters
