New DC-DC Power Module offers higher voltages for industrial applications


Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the MAXM17552 compact step-down DC-DC power module from Maxim Integrated. Offering an ultra-small power source to drive high-voltage industrial and consumer applications, the micro system-level IC (uSLIC) module provides a wide input voltage range for factory automation, medical, and communications devices.

The Maxim MAXM17552 module, available from Mouser Electronics, is part of Maxim’s Himalaya series of voltage regulator ICs and power modules, which enable cooler, smaller, and simpler power supply solutions. The MAXM17552 module operates over a wide input-voltage range of 4 V to 60 V and delivers up to 100 mA output current over an adjustable output voltage from 0.9 V to 5.5 V. The module integrates a synchronous wide-input Himalaya buck regulator with built-in FETs, compensation and other functions with an integrated shielded inductor in a miniscule 2.6 mm × 3.0 mm × 1.5 mm package. 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 MAXM17552 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.
