MAXM17544

4.5V to 42V, 3.5A High-Eﬃciency, DC-DC Step-

Down Power Module with Integrated Inductor

General Description

Beneﬁts and Features

● Reduces Design Complexity, Manufacturing Risks,

and Time-to-Market

The Himalaya series of voltage regulator ICs, power mod-

ules, and chargers enable cooler, smaller, and simpler

power supply solutions. The MAXM17544 is an easy-to-

use, Himalaya step-down power module that combines

a switching power supply controller, dual n-channel

MOSFET power switches, fully shielded inductor, and the

compensation components in a low-profile, thermally-effi-

cient, system-in-package (SiP). The device operates over

a wide input voltage range of 4.5V to 42V and delivers up to

3.5A continuous output current with excellent line and load

regulation over an output voltage range of 0.9V to 12V.

The device only requires five external components to com-

plete the total power solution. The high level of integration

significantly reduces design complexity, manufacturing

risks, andoffersatrueplug-and-playpowersupplysolution,

reducing time-to-market.

• Integrated Switching Power Supply Controller and

Dual-MOSFET Power Switches

• Integrated Inductor

• Integrated Compensation Components

● Saves Board Space in Space-Constrained Applications

• Complete Integrated Step-Down Power Supply in a

Single Package

• Small Proﬁle 9mm x 15mm x 2.8mm SiP Package

• Simpliﬁed PCB Design with Minimal External BOM

Components

● Offers Flexibility for Power-Design Optimization

• Wide Input Voltage Range from 4.5V to 42V

• Output-Voltage Adjustable Range from 0.9V to 12V

• Adjustable Frequency with External Frequency

Synchronization (100kHz to 1.8MHz)

• Soft-Start Programmable

• PWM, PFM, or DCM Current-Mode Control

• Optional Programmable EN/UVLO

● Operates Reliably in Adverse Industrial Environments

• Integrated Thermal Fault Protection

• Hiccup Mode Overload Protection

The device can be operated in the pulse-width modulation

(PWM), pulse-frequency modulation (PFM), or discontinuous

conduction mode (DCM) control schemes.

The MAXM17544 is available in a low-profile, highly

thermal-emissive, compact, 29-pin 9mm x 15mm x 2.8mm

SiP package that reduces power dissipation in the

package and enhances efficiency. The package is

easily soldered onto a printed circuit board and suitable

for automated circuit board assembly. The device can

operate over wide industrial temperature range from

-40°C to +125°C.

• RESET Output-Voltage Monitoring

• High Industrial Ambient Operating

Temperature Range (-40°C to +125°C)/unction

Temperature Range (-40°C to +150°C)

• Complies with CISPR22(EN55022) Class B

Conducted and Radiated Emissions

Typical Application Circuit

Applications

● Industrial Power Supplies

4.5V TO 42V

● Distributed Supply Regulation

● FPGA and DSP Point-of-Load Regulator

● Base Station Point-of-Load Regulator

● HVAC and Building Control
