MAX20812

Dual-Output, 6A, 3MHz, 2.7V to 16V, Step-Down

Switching Regulator

General Description

Benefits and Features

The MAX20812 is a dual-output, fully integrated, highly

efficient, step-down DC-DC switching regulator. This

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.

•

High Power Density with Low Component Count

• Dual-Output or Dual-Phase Operation

• Single-Supply Operation with Integrated LDO for

Bias Generation

• Optional 2.5V to 5.5V External Bias for Higher

Efficiency

• Compact 3.5mm x 4.6mm, 21-Pin, FC2QFN

Package

• Internal Compensation

Wide Operating Range

The switching frequency of this device can be configured

from 500kHz to 3.0MHz and provides the capability of

optimizing the design in terms of solution size and

performance.

• 2.7V to 16V Input Voltage Range

• 0.5V to 5.8V Output Voltage Range

• 500kHz to 3MHz Configurable Switching

Frequency

• -40°C to +125°C Junction Temperature Range

• Three Pin-Strap Programming Pins to Select

Different Configurations

• Independent Enable and Power Good for Each

Output

Optimized Performance and Efficiency

The MAX20812 utilizes fixed-frequency, current-mode

control with internal compensation. The dual-switching

regulators operate 180° out-of-phase. The MAX20812

features a selectable advanced modulation scheme

(AMS) to provide improved dynamic load transient

performance. The device also features selectable

discontinuous current mode (DCM) operation to improve

light load efficiency. Operation settings and configurable

features can be selected by connecting pin-strap

resistors from the PGM_ pins to ground.

• Selectable AMS to Improve Load Transient

• Selectable DCM to Improve Light Load Efficiency

• Active Current Balancing for Dual-Phase

Operation

The MAX20812 has an internal 1.8V LDO output to

power the gate drives (V ) and internal circuitry

(AVDD). The device also has an optional LDO input pin

(LDOIN), allowing connection from a 2.5V to 5.5V bias

input supply for optimized efficiency.

Electrical and Thermal Ratings

The MAX20812 integrates multiple protections including

positive and negative overcurrent protection, output

overvoltage protection, and overtemperature protection

to ensure a robust design.
