High-Efficiency, 2A, Current-Mode  
Synchronous, Step-Down Switching Regulator  
General Description  
Features  
High-Side and 18mI  
The MAX15053 high-efficiency, current-mode, synchro-  
nous step-down switching regulator with integrated  
power switches delivers up to 2A of output current.  
The device operates from 2.7V to 5.5V and provides an  
output voltage from 0.6V up to 94% of the input voltage,  
making the device ideal for distributed power systems,  
portable devices, and preregulation applications.

(typ) Low-Side MOSFETs at 5V  
S Continuous 2A Output Current Over Temperature  
S 96% Efficiency with 3.3V Output at 2A

S Operates from 2.7V to 5.5V Supply  
S Cycle-by-Cycle Overcurrent Protection  
S Adjustable Output from 0.6V to Up to 0.94 x V  
S Programmable Soft-Start  
The MAX15053 utilizes a current-mode control archi-  
tecture with a high gain transconductance error ampli-  
fier. The current-mode control architecture facilitates  
easy compensation design and ensures cycle-by-cycle  
current limit with fast response to line and load transients.

ciency at light output load. The low R  
integrated  
DS(ON)  
switches ensure high efficiency at heavy loads while min-  
imizing critical inductances, making the layout design  
a much simpler task with respect to discrete solutions.  
Utilizing a simple layout and footprint assures first-pass  
success in new designs.  
S Skip-Mode Functionality  
S Enable Input/Power-Good Output  
S Fully Protected Against Overcurrent and  
The MAX15053 features a 1MHz, factory-trimmed, fixed-  
frequency PWM mode operation. The high switching fre-  
quency, along with the PWM current-mode architecture,  
allows for a compact, all-ceramic capacitor design.

Ordering Information  
The MAX15053 offers a capacitor-programmable soft-  
start reducing inrush current, startup into PREBIAS  
operations, and a PGOOD open-drain output that can be  
used as an interrupt and for power sequencing.
