Provides a maximum voltage range of 4~60V
Compliant with CISPR 22 Class B EMI standards

In system design, product miniaturization remains an important factor, but a wide input voltage range must also be considered.

The supply voltage of factory automation equipment is highly sensitive to large fluctuations due to long transmission lines. USB-C and various 12V applications require up to 24V operating voltage protection against transients due to hot-plugging of power supply devices and batteries.
Accordingly, Maxim Integrated Korea launched a microsystem-level IC module applicable to factory automation, medical equipment, communications, and consumer products on October 29. The ultra-small step-down DC-DC power module has been newly added to Maxim's Himalaya ultra-small system unit IC (uSLIC) family, enabling the provision of a maximum voltage range of 4 to 60 V in the industry's smallest size solution.

The maximum voltage of the latest Himalaya uSLIC power module has increased from the existing 42V to 60V. The solution size is 2.6mm x 3.0mm x 1.5mm. This module provides a synchronous wide-input Himalaya buck regulator and features an integrated shielded inductor along with built-in FETs, compensation, and other functions. This enables power supply designs that meet power, solution size, radiation, and temperature requirements within hours.

The Himalaya uSLIC power module is an EMI-compliant solution. It complies with the CISPR 22 (EN 5022) Class B EMI standard and does not require power supply redesign. It is JEDEC certified and highly durable against drops, impacts, and vibrations.

The latest Himalaya uSLIC modules include: ▲MAXM17552: 4–60V, 100mA module, 100–900kHz variable switching frequency, 82% efficiency (24V VIN at 5V/0.1A), provides external clock synchronization ▲MAXM15064: 4.5–60V, 300mA module, 500kHz fixed frequency, 82% efficiency (24V VIN at 5V/0.1A), provides built-in output voltage monitoring ▲MAXM17900: 4–24V, 100mA module, 100–900kHz variable switching frequency, 86% efficiency (12V VIN at 5V/100mA), external clock synchronization, provides built-in output voltage monitoring ▲MAXM17903: 4.5–24V, 300mA module, 500kHz fixed switching frequency, 77% Efficiency (12V VIN at 3.3V/300mA) and built-in output voltage monitoring are included.

Chuck Dolezalek, Senior Engineering Director of the Lighting Group at Banner Engineering, stated, “With the Maxim Himalaya uSLIC module, we are now able to add next-generation features to Banner Engineering’s K30 lighting touch button enclosure without increasing its size.”

David Stein, Vice President of Global Supply Management at Digi-Key Electronics, stated, “While industrial and consumer system designs are becoming smaller, there is a continuing demand for wide input voltage ranges. Maxim’s Himalaya uSLIC power module portfolio provides the industry’s largest input voltage range of 4 to 60V as an ultra-small size solution.” "Through this, we can support designers and customers developing space-constrained applications and simultaneously resolve issues regarding power consumption and efficiency," they stated.

Viral Vaidya, General Manager of Business Management for the Industrial Power Business at Maxim Integrated, stated, “As new power requirements increase, ranging from consumer products to factories adopting Industry 4.0, Maxim is making significant efforts to provide innovative solutions. The newly launched Himalaya uSLIC product family will play a key role amidst industry changes.”
