Datasheet

Offering an ultra-small power source to drive high-voltage industrial and consumer applications, the MAXM17552 compact step-down DC-DC power module from Maxim Integrated is available at Mouser Electronics. The micro system-level IC (uSLIC) module provides a wide input voltage range for factory automation, medical, and communications devices.

The module is part of Maxim's Himalaya series of voltage regulator ICs and power modules, which enable cooler, smaller, and simpler power supply solutions.

It operates over a wide input-voltage range of 4V to 60V and delivers up to 100mA output current over an adjustable output voltage from 0.9 V to 5.5 V. It integrates a synchronous wide-input Himalaya buck regulator with built-in FETs, compensation and other functions with an integrated shielded inductor in a minuscule 2.6 mm × 3.0 mm × 1.5 mm package.

In addition, the module uses peak-current-mode control architecture, operates in pulse-width modulation (PWM) mode, and offers a soft-start feature to reduce input inrush current.

Compliant to CISPR 22 (EN 5022) Class B and JEDEC certified, the power module delivers increased energy efficiency, shock and vibration tolerance, high temperature operation, and electromagnetic interference (EMI) compliance.

The devices boast an ambient operating temperature range of minus 40 to 125 degrees Celsius and are guarded by hiccup overcurrent protection and overtemperature protection.

Ideal for space-constrained applications in small enclosures, the modules offer a power solution to support industrial sensors, motor encoders, building control, 4mA to 20mA current-loop powered sensors, and low dropout (LDO) regulator replacement.
