The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2355 is a step-down regulator with a  
built in internal Power MOSFET. It achieves 3A  
continuous output current over a wide input  
supply range with excellent load and line  
regulation.  
Programmable Soft-Start  
100mInternal Power MOSFET Switch  
Stable with Low ESR Output Ceramic  
Capacitors  
Up to 95% Efficiency  
20µA Shutdown Mode  
Current mode operation provides fast transient  
response and eases loop stabilization. Fault  
condition protection includes cycle-by-cycle  
current limiting and thermal shutdown. Adjustable  
soft-start reduces the stress on the input source  
at turn-on. In shutdown mode the regulator draws  
20µA of supply current.  
3A Output Current  
Wide 4.75V to 23V Operating Input Range  
Fixed 380KHz Frequency  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Under Voltage Lockout  
The MP2355 uses a minimum number of  
readily available external components to  
complete a 3A step-down DC to DC converter  
solution.  
APPLICATIONS  
Distributed Power Systems  
Battery Chargers  
Pre-Regulator for Linear Regulators
