EVALUATION KIT AVAILABLE  
MAX15058  
High-Efficiency, 3A, Current-Mode Synchronous,  
Step-Down Switching Regulator  
General Description  
Features  
● Internal 30mΩ (typ) R  
The MAX15058 high-efficiency, current-mode, synchro-  
nous step-down switching regulator with integrated power  
switches delivers up to 3A of output current. The device  
operates from 2.7V to 5.5V and provides an output volt-  
age from 0.6V up to 94% of the input voltage, making  
the device ideal for distributed power systems, portable  
devices, and preregulation applications.  
High-Side and 18mΩ  
DS(ON)  
(typ) Low-Side MOSFETs at 5V  
● Continuous 3A Output Current Over Temperature  
● 95% Efficiency with 3.3V Output at 3A  
● 1% Output Voltage Accuracy Over Load, Line, and  
Temperature  
● Operates from 2.7V to 5.5V Supply  
● Cycle-by-Cycle Overcurrent Protection  
The MAX15058 utilizes a current-mode control architec-  
ture with a high-gain transconductance error amplifier.  
The current-mode control architecture facilitates easy  
compensation design and ensures cycle-by-cycle current  
limit with fast response to line and load transients.  
● Adjustable Output from 0.6V to Up to 0.94 x V  
● Programmable Soft-Start

● Factory-Trimmed, 1MHz Switching Frequency  
The MAX15058 offers selectable skip-mode functional-  
ity to reduce current consumption and achieve a higher  
● Stable with Low-ESR Ceramic Output Capacitors  
● Safe-Startup Into Prebiased Output  
● External Reference Input  
efficiency at light output load. The low R  
integrated  
DS(ON)  
switches ensure high efficiency at heavy loads while  
minimizing 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.  
● Skip-Mode Functionality  
● Enable Input/Power-Good Output  
● Fully Protected Against Overcurrent and  
The MAX15058 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.  
Overtemperature  
● Input Undervoltage Lockout  
Ordering Information  
The MAX15058 offers a capacitor-programmable soft-  
start reducing inrush current, startup into PREBIAS opera-  
tions, and a PGOOD open-drain output that can be used  
as an interrupt and for power sequencing.
