High-Efficiency, 6A, Current-Mode  
Synchronous Step-Down Switching Regulator

MAX15106C  
General Description  
Features  
Continuous 6A Output Current  
The MAX15106A/MAX15106B/MAX15106C family of  
high-efficiency, current-mode, synchronous step-down  
switching regulators with integrated power switches deliver  
up to 6A of output current. The regulators operate from  
2.7V to 5.5V and provide an output voltage from 0.6V  
up to 95% of the input voltage, making the devices ideal  
for distributed power systems, portable devices, and pre-  
regulation applications.  
Efficiency Up to 96%  
±1% Accuracy Over Load, Line, and Temperature  
Operates from a 2.7V to 5.5V Supply  
Adjustable Output from 0.6V to 0.95 × V  
Programmable Soft-Start  
IN  
Safe Startup into Prebiased Output  
External Reference Input  
The ICs utilize 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.  
0.9MHz, 1.0MHz, and 1.1MHz Switching Frequency  
Options  
Stable with Low-ESR Ceramic Output Capacitors  
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 ICs’ simple layout and  
footprint assures first-pass success in new designs.  
Enable Input and Power-Good Output for Power-  
Supply Sequencing  
Cycle-by-Cycle Overcurrent Protection  
The regulator features 0.9MHz (MAX15106A), 1.0MHz  
(MAX15106B), and 1.1MHz (MAX15106C) 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.  
Fully Protected Features Against Overcurrent and  
Overtemperature  
Input Undervoltage Lockout  
20-Bump (4 x 5 Array), 2.5mm x 2mm, WLP Package  
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.
