The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power supply solutions. The MAXM17633, MAXM17634, and MAXM17635 are a family of high-frequency synchronous step-down DC-DC converter modules with integrated controller, MOSFETs, compensation components, and inductor, that operate over a wide input voltage range. The modules operate from 4.5V to 36V input and deliver up to 2A output current. MAXM17633 and MAXM17634 are fixed 3.3V and 5V output modules, respectively. The MAXM17635 is an adjustable-output voltage (0.9V to 12V) module. The modules significantly reduce design complexity, manufacturing risks, and offer a true plug-and-play power supply solution, reducing time to market.

The MAXM17633/MAXM17634/MAXM17635 modules employ peak-current-mode control architecture. To reduce input inrush current, the devices offer a programmable soft-start time.

The MAXM17633/MAXM17634/MAXM17635 modules are available in a low profile, compact 24-pin, 4mm x 4mm x 1.75mm, uSLIC™ package.

Applications

  • Industrial Control Power Supplies
  • General-Purpose Point-of-Load
  • Distributed Supply Regulation
  • Base Station Power Supplies
  • Programmable Logic Controller
  • High Voltage Single-Board Systems
