DESCRIPTION  
FEATURES  
The MP1591 is a high voltage step-down  
converter ideal for automotive power adapter  
battery chargers. Its wide 6.5V to 32V input  
voltage range covers the automotive battery’s  
requirements and it achieves 2A continuous  
output for quick charge capability.  
Wide 6.5V to 32V Input Operating Range  
34V Absolute Maximum Input  
2A Output Current  
120mInternal Power MOSFET Switch  
Stable with Low ESR Output Ceramic  
Capacitors  
Up to 95% Efficiency  
20µA Shutdown Mode  
Fixed 330KHz Frequency  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Output Adjustable From 1.23V to 21V  
Under Voltage Lockout  
Reference Voltage Output  
Available in 8-Pin SOIC Packages  
Current mode operation provides fast transient  
response and eases loop stabilization. Fault  
protection includes cycle-by-cycle current  
limiting and thermal shutdown. In shutdown  
mode, the converter draws only 20µA of supply  
current.  
The MP1591 requires a minimum number of  
readily available external components to  
complete a 2A step-down DC to DC converter  
solution.
