MP2495  
Integrated 100V Load Dump Protection, 2A Step  
Down Regulator with Output Current Control  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
Replaces External Transorb  
The MP2495 is a monolithic step-down switch  
mode converter with a programmable output  
current limit and an integrated input over-  
voltage protection switch It achieves 2.0A  
continuous output current over a wide input  
supply range with excellent load and line  
regulation.  
Input Surge Protection Up to 100V  
Programmable up to 2.0A Output Current  
Output Adjustable from 0.8V to 15V  
Programmable Output Current Limit without  
power loss  
0.25Internal Power MOSFET Switch  
Stable with Low ESR Output Ceramic  
Capacitors  
The maximum output current can be  
programmed by sensing current through the  
inductor DC resistance (DCR) or an accurate  
sense resistor.  
95% Efficiency @ 500mA (Vo=5V)  
Fixed 700kHz Frequency  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Available in a 16-Pin SOIC Package  
Fault condition protection includes cycle-by-cycle  
current limiting and thermal shutdown.  
The MP2495 can survive high-voltage transients  
such as those found in automotive and industrial  
applications.  
APPLICATIONS  
USB Power Supplies  
Automotive Cigarette Lighter Adapters  
Power Supply for Linear Chargers  
The MP2495 requires a minimum number of  
readily available standard external components.  
The MP2495 is available in a 16-pin SOIC package.
