MAXM17545

4.5V to 42V, 1.7A 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, and power

modules, and chargers enable cooler, smaller, and simpler

power supply solutions. The MAXM17545 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 compen-

sation components in a low-profile, thermally-efficient,

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

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

1.7A 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 complete

the total power solution. The high level of integration signifi-

cantly reduces design complexity, manufacturing risks, and

offers a true plug-and-play power supply solution, reducing

time-to-market.

• Integrated Switching Power Supply Controller and

Dual-MOSFET Power Switches

• Integrated Inductor

• Integrated Compensation Components

• Integrated Thermal-Fault Protection

• Integrated Peak Current Limit

● 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)

The device can be operated in the pulse-width modulation

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

conduction mode (DCM) control schemes.

• Soft-Start Programmable

• PWM, PFM, or DCM Current-Mode Control

• Optional Programmable EN/UVLO

The MAXM17545 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, while enhancing 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.

● Operates Reliably in Adverse Industrial Environments

• Integrated Thermal Fault Protection

• Hiccup Mode Overload Protection

• RESET/ Output-Voltage Monitoring

• Wide Industrial Ambient Operating Temperature

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

Range (-40°C to +150°C)

• Complies with CISPR22(EN55022) Class B

Conducted and Radiated Emissions

Applications

● Industrial Power Supplies

● Distributed Supply Regulation

● FPGA and DSP Point-of-Load Regulator

● Base Station Point-of-Load Regulator

● HVAC and Building Control
