Maxim expands its Himalaya uSLIC module family with widest input voltage range and smallest size

By Gina Roos, editor-in-chief

Maxim Integrated Products, Inc. has expanded
its Himalaya power offering with four new step-down power modules, touting the
widest input voltage range (4 V to 60 V) with the smallest solution sizes. The
new micro-system-level IC (uSLIC) modules include the MAXM17552, MAXM15064, MAXM17900 and MAXM17903. Target
applications include factory automation, medical, communications, and consumer
markets.
 

With
the latest uSLIC power modules Maxim has expanded the voltage range up to 60 V
compared to the previous maximum of 42 V in a 2.6 mm x 3.0 mm x 1.5 mm footprint.
The company said the footprint is less than half the size of the closest
competitive offering.

The
expanded voltage range allows the devices to be used in a variety of system
designs that require a wide range of input voltages. Maxim cited a few examples
including supply voltages in factory automation equipment that are susceptible
to large fluctuations due to long transmission lines, and USB-C and broad 12-V
nominal applications that require up to 24 V of working voltage protection against
transients due to hot plugging of supplies and/or batteries.

 

Key
module features include a synchronous wide-input Himalaya buck regulator with
built-in FETs, compensation and other functions with an integrated shielded
inductor. “Having the inductor in the module simplifies the toughest aspect of
power supply design, enabling designers—even those with little power
expertise—to create a robust, reliable power supply in less than a day,” said
Maxim.

“One
of the toughest design challenges for inexperienced designers is to choose an
inductor which will meet the power, size, emission and temperature requirements
for a given design,” Maxim added. “Himalaya uSLIC modules have an integrated
shielded inductor which conforms to the standards of the datasheet, meeting all
electrical requirements and allowing designers to build a power supply in a few
hours. Getting a fully working power supply can be as easy as choosing the
input and output capacitor and setting the output voltage through the resistor
divider network.”

The
new uSLIC modules include:

  • MAXM17552, a 4 V to 60 V, 100 mA module with 100 to 900 kHz adjustable
    switching frequency, 82% efficiency (24-V VIN at 5 V/0.1 A) and
    external synchronization frequency in a 2.6-mm x 3-mm x 1.5-mm package
  • MAXM15064, a 4.5 V to 60 V, 300 mA module with 500 kHz adjustable
    switching frequency, 82% efficiency (24-V VIN at 5V/0.1A), external
    synchronization frequency and built-in output voltage monitoring in a 2.6-mm x
    3-mm x 1.5-mm package
  • MAXM17900, a 4 V to 24 V, 100 mA module with 100 to 900 kHz
    adjustable switching frequency, 86% efficiency (12-V VIN at 5 V/100 mA),
    external synchronization frequency and built-in output voltage monitoring in a 2.6-mm
    x 3-mm x 1.5-mm package
  • MAXM17903, a 4.5 V to 24 V, 300 mA module with 500 kHz fixed
    switching frequency, 77% efficiency (12-V VIN at 3.3V/300mA),
    external synchronization frequency and built-in output voltage monitoring in a 2.6-mm
    x 3-mm x 1.5-mm package

The
modules are compliant to CISPR 22 (EN 5022) Class B EMI, and are JEDEC certified
to withstand drop, shock and vibration.

Module pricing (1000-up, FOB USA) includes:

  • $2.53 for the MAXM17552
  • $2.78 for the MAXM15064
  • $1.39 for the MAXM17900
  • $1.48 for the MAXM17903

The MAXM17552EVKIT#, MAXM15064EVKIT#, MAXM17900EVKIT# and MAXM17903EVKIT# evaluation
kits are priced at $29.73 each. EE-Sim models are available.
