EVALUATION KIT AVAILABLE

MAX18066/MAX18166

High-Eﬃciency, 4A, Step-Down DC-DC

Regulators with Internal Power Switches

General Description

Beneﬁts and Features

The MAX18066/MAX18166 current-mode, synchronous,

DC-DC buck converters deliver an output current up

to 4A with high efficiency. The devices operate from

an input voltage of 4.5V to 16V and provides an

adjustable output voltage from 0.606V to 90% of the

input voltage. The devices are ideal for distributed power

systems, notebook computers, nonportable consumer

applications, and preregulation applications.

● Feature Integration Shrinks Solution Size

• Integrated 40mΩ (High-Side) and 18.5mΩ

(Low-Side) R

Power MOSFETs

DS-ON

• Stable with Low-ESR Ceramic Output Capacitors

• Enable Input and Power-Good Output

• Cycle-by-Cycle Overcurrent Protection

• Fully Protected Against Overcurrent

(Hiccup Protection) and Overtemperature

● High Efficiency Conserves Power

The devices feature a PWM mode operation with

an internally fixed switching frequency of 500kHz

(MAX18066) and 350kHz (MAX18166) capable of 90%

maximum duty cycle. The devices automatically enter

skip mode at light loads. The current-mode control

architecture simplifies compensation design and ensures

a cycle-by-cycle current limit and fast response to line

and load transients. A high-gain transconductance error

amplifier allows flexibility in setting the external com-

pensation, simplifying the design and allowing for an all-

ceramic design.

• Up to 96% Eﬃciency (5V Input and 3.3V Output)

• Up to 93% Eﬃciency (12V Input and 3.3V Output)

• Automatic Skip Mode During Light Loads

● Safe, Reliable, Accurate Operation

• Continuous 4A Output Current

• ±1% Output Accuracy over Load, Line, and

Temperature

• Safe Startup Into Prebiased Output

• Programmable Soft-Start

• V

LDO Undervoltage Lockout

● Well Suited to Distributed Power, Networking, and

The synchronous buck regulators feature inter-

nal MOSFETs that provide better efficiency than

asynchronous solutions, while simplifying the design

relative to discrete controller solutions. In addition to

simplifying the design, the integrated MOSFETs minimize

EMI, reduce board space, and provide higher reliability by

minimizing the number of external components.

Computing Applications

• 4.5V to 16V Input Voltage Range

• Adjustable Output Voltage Range from 0.606V

to (0.9 x V )

● Available in EE-Sim^®Design and Simulation Tool to

Slash Design Time

Additional features include an externally adjustable

soft-start, independent enable input and power-good

output for power sequencing, and thermal shutdown

protection. The devices offer overcurrent protection (high-

side sourcing) with hiccup mode during an output short-

circuit condition. The devices ensure safe startup when

powering into a prebiased output.
