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.

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.
