Product Details
The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler powersupply solutions. The MAXM17552 is a high-efficiency, synchronous, step-down DC-DC power module with integrated controller, MOSFETs, compensation components, and inductor that operates over a wide input-voltage range. The module operates from 4V to 60V input voltage and delivers up to 100mA output current over a programmable output voltage from 0.9V to 5.5V. The module significantly reduces design complexity, manufacturing risks and offers a true “plug and play” power supply solution, reducing the time-to-market.
The MAXM17552 employs peak-current-mode control architecture. To reduce input inrush current, the device offers a soft-start feature including the default soft-start time of 5.1ms.
The MAXM17552 is available in a low profile, compact 10-pin 2.6mm x 3mm x 1.5mm µSLIC™ package.

Description
The MAXM17552 evaluation kit (EV kit) is a demonstration circuit of the MAXM17552 ultra-small, high efficiency, current mode, synchronous step-down DC-DC switching power module. The EV kit operates over a wide input-voltage of 14V to 60V and provides up to 100mA load current with a 5V output voltage. The EV kit is programmed to switch at a frequency of 450kHz. The module is simple to use and easily configurable with minimal external components. It features cycle-bycycle peak current-limit protection, undervoltage lockout (EN/UVLO), and thermal shutdown.
The EV kit comes with the compact 10-pin 2.6mm x 3mm x 1.5mm uSLIC™ package MAXM17552 module installed, and is rated to operate over the full industrial/ automotive -40°C to +125°C temperature range. For full specifications, features and benifits of the IC, refer to the MAXM17552 data sheet.
