MAXM17543  
4.5V to 42V, 2.5A High-Efficiency, DC-DC Step-  
Down Power Module with Integrated Inductor  
General Description  
Benefits and Features  
● Reduces Design Complexity, Manufacturing Risks,  
The Himalaya series of voltage regulator ICs, power  
modules, and chargers enable cooler, smaller, and sim-  
pler power supply solutions. The MAXM17543 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 induc-  
tor, and the compensation components in a low-pro-  
file, thermally-efficient, system-in-package (SiP). The  
device operates over a wide input voltage range of  
4.5V to 42V and delivers up to 2.5A continuous output  
currentwithexcellentlineandloadregulationoveranoutput  
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 significantly reduces  
design complexity, manufacturing risks, and offers a true  
plug-and-play power supply solution, reducing time-to-  
market.  
and Time-to-Market  
• Integrated Switching Power Supply Controller and  
Dual-MOSFET Power Switches  
• Integrated Inductor  
• Integrated Compensation Component  
● 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  
The device can be operated in the pulse-width modulation  
(PWM), pulse-frequency modulation (PFM), or discontinuous  
conduction mode (DCM) control schemes.  
● Operates Reliably in Adverse Industrial Environments  
The MAXM17543 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 the industrial temperature range from -40°C  
to +125°C.  
• 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 Con-  
ducted and Radiated Emissions  
Applications  
● Industrial Power Supplies  
Typical Application Circuit  
● Distributed Supply Regulation  
● FPGA and DSP Point-of-Load Regulator  
● Base Station Point-of-Load Regulator  
● HVAC and Building Control
