MAXM17505  
4.5V to 60V, 1.7A High-Efficiency, DC-DC Step-  
Down Power Module with Integrated Inductor  
Saves Board Space in Space-Constrained  
Applications  
General Description  
The Himalaya series of voltage regulator ICs, power mod-  
ules, and chargers enable cooler, smaller, and simpler  
power supply solutions. The MAXM17505 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-  
efficient, system-in-package (SiP). The device operates  
over a wide input voltage range of 4.5V to 60V and deliv-  
ers 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 significantly reduces design  
complexity, manufacturing risks, and offers a true plug-  
and-play power supply solution, reducing time-to-market.  
• 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 60V  
• 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 modu-  
lation (PWM), pulse-frequency modulation (PFM), or  
discontinuous conduction mode (DCM) control schemes.  
• RESET/Output-Voltage Monitoring  
• Wide Industrial Ambient Operating Temperature  
Range (-40°C to +125°C)/Junction Temperature  
Range (-40°C to +150°C)  
The MAXM17505 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 a wide industrial temperature range from  
-40°C to +125°C.
