EVALUATION KIT AVAILABLE  
MAX15108A  
High-Efficiency, 8A, Current-Mode  
Synchronous Step-Down Switching Regulator  
General Description  
Features  
The MAX15108A high-efficiency, current-mode, syn-  
chronous step-down switching regulator with integrated  
power switches delivers up to 8A of output current. The  
regulator operates from 2.7V to 5.5V and provides an  
output voltage from 0.6V up to 95% of the input voltage,  
making the device ideal for distributed power systems,  
portable devices, and preregulation applications.  
S Continuous 8A Output Current  
S Efficiency Up to 96%  
S
1% Accuracy Over Load, Line, and Temperature  
S Operates from a 2.7V to 5.5V Supply  
S Adjustable Output from 0.6V to 0.95 x V  
S Programmable Soft-Start  
IN  
The IC utilizes a current-mode control architecture  
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.  
S Safe Startup into Prebiased Output  
S External Reference Input  
S 1MHz Switching Frequency  
S Stable with Low-ESR Ceramic Output Capacitors  
S Forced PWM Mode  
The low R  
integrated switches ensure high effi-  
DS(ON)  
ciency at heavy loads while minimizing critical induc-  
tance, making the layout design a much simpler task  
with respect to discrete solutions. The IC’s simple layout  
and footprint assures first-pass success in new designs.  
S Enable Input and Power-Good Output for Power-  
Supply Sequencing  
S Cycle-by-Cycle Overcurrent Protection  
S Fully Protected Features Against Overcurrent and  
The regulator features a 1MHz, factory-trimmed fixed-  
frequency PWM mode operation. The high switching  
frequency, along with the PWM current-mode architecture  
allows for a compact, all ceramic capacitor design.  
Overtemperature  
S Input Undervoltage Lockout  
S 20-Bump (4 x 5 Array), 2.5mm x 2mm, WLP  
The IC features a capacitor-programmable soft-start  
to reduce input inrush current. Internal control circuitry  
ensures safe-startup into a prebiased output. Power  
sequencing is controlled with the enable input and  
power-good output.
