DC/DC buck modules

The simplest and smallest option for step-down DC/DC voltage conversion

DC/DC step-down power modules integrate inductors, FETs, compensation, and other passive components into a single package to simplify the design process and speed customer time-to-market with a minimized power supply footprint. We feature the industry's most diverse portfolio of step-down modules, reaching 60 VIN and 60 A with a variety of packaging options to choose from.

simplify your DC/DC design


Our integrated-inductor step-down power modules greatly simplify the process of DC/DC design compared to discrete converter and controller ICs.

  • Optimal converter selected for the specification
  • Reduced component sourcing and qualification
  • Optimized layout for EMI and thermal performance
  • Fully characterized across the operating range
shrink your DC/DC design


DC/DC buck modules minimize power supply solution size to maximize power density and meet challenging PCB area constraints.

  • Integrated controller, FETs, inductor, passives
  • IC package sizes as small as 2.3 mm x 2.9 mm
  • Up to 40% PCB area reduction compared to discrete
