MAX16712  
Dual-Output, 6A, 2MHz, 2.7V to 16V  
Step-Down Switching Regulator  
Benefits and Features  
General Description  
High Power Density with Low Component Count  
Dual-Output or Dual-Phase Operation  
Single-Supply Operation with Integrated LDO for  
Bias Generation  
The MAX16712 is a dual-output, fully integrated, highly  
efficient, step-down DC-DC switching regulator. The  
device operates from 2.7V to 16V input supplies, and  
each output can be regulated from 0.5V to 5.8V. The IC  
delivers up to 6A of load current per output. The two  
outputs can be connected in parallel as a single-output,  
dual-phase regulator that supports up to 12A load  
current.  
Compact 2.2mm x 3.5mm, 28-Bump WLP  
Internal Compensation  
Wide Operating Range  
2.7V to 16V Input Voltage Range  
0.5V to 5.8V Output Voltage Range  
500kHz to 2MHz Configurable Switching  
Frequency  
The switching frequency of the device can be configured  
from 500kHz to 2.0MHz and provides the capability of  
optimizing the design in terms of solution size and  
performance.  
-40°C to +125°C Junction Temperature Range  
Three Programming Pins to Select Different  
Configurations  
Independent Enable and Power Good for Each  
Output  
The MAX16712 utilizes fixed-frequency, current-mode  
control with internal compensation. The dual-switching  
regulators operate 180° out-of-phase. The IC features  
an advanced modulation scheme (AMS) and selectable  
discontinuous current mode (DCM) operation to provide  
improved performance. Operation settings and  
configurable features can also be selected by  
connecting a pin-strap resistor from PGM0 pin to ground.

Active Current Balancing for Dual-Phase Operation  
The MAX16712 has an internal 1.8V LDO output to  
power the gate drives (V ) and internal circuitry  
CC  
(AVDD).  
The MAX16712 integrates multiple protections including  
positive and negative overcurrent protection, output  
overvoltage protection and overtemperature protection  
to ensure robust design.
