EVALUATION KIT AVAILABLE

MAX17558

60V, Dual-Output, Synchronous

Step-Down Controller

General Description

The MAX17558 is a dual-output, synchronous step-down

Beneﬁts and Features

● Wide Range of Operation

controller that drives nMOSFETs.

• Wide 4.5V to 60V Input Voltage Range

• Wide 0.8V to 24V Output Voltage Range

The device features a peak-current-mode, constant-

frequency architecture, allowing it to operate up to

2.2MHz. The device can be configured as two single-

phase, independent 10A power supplies or as a dual-

phase, single-output 20A power supply. The device also

provides the ability to run two controllers 180° out-of-

phase to reduce the power loss and noise due to the

input-capacitor ESR.

• R

or Inductor DCR Current Sensing

SENSE

• Selectable In-Phase or 180° Out-of-Phase

Operation

• Adjustable 100kHz to 2.2MHz Switching Frequency

• Independent Enable and PGOOD

• Available in a Lead(Pb)-Free 32-Pin, 5mm x 5mm

TQFN-EP Package

● Enhances Power Efficiency

The IC supports current sensing using either an external

current-sense resistor for accuracy or an inductor DCR

for improved system efficiency. Current foldback limits

MOSFET power dissipation under short-circuit conditions.

• Low-Impedance Gate Drives for High Efficiency

• DCM Operation at Light Loads

• Auxiliary Bootstrap LDO

● Operates Reliably in Adverse Industrial Environments

• Independent Adjustable Soft-Start or Tracking

• Current Foldback Limits MOSFET Heat Dissipation

During a Short-Circuit Condition

The IC provides independent adjustable soft-start for

each output and can start up monotonically into a

prebiased output. The IC can be configured in either

PWM or DCM modes of operation, depending on whether

constant-frequency operation or light-load efficiency is

desired.

• Operates Over the -40°C to +125°C Temperature

Range

• Output Overvoltage and Overtemperature Protections

The IC operates over the -40°C to +125°C temperature

range and is available in a lead(Pb)-free, 32-pin TQFN,

5mm x 5mm package with an exposed pad.

Ordering Information appears at end of data sheet.

Applications

● Industrial Power Supplies

● Distributed DC Power Systems

● Motion Control

● Programmable Logic Controllers

● Computerized Numerical Control
