MAX15066/MAX15166

High-Efﬁciency, 4A, Step-Down DC-DC

Regulators with Internal Power Switches

General Description

Beneﬁts and Features

● Feature Integration Shrinks Solution Size

The MAX15066/MAX15166 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.

• 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

(MAX15066) and 350kHz (MAX15166) 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

compensation, 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 mini-

mize EMI, reduce board space, and provide higher reli-

ability 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.
