DC/DC buck modules

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

DC/DC buck 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. TI features the industry's most diverse portfolio of step-down modules, reaching 60VIN and 60A with a variety of packaging options to choose from.

Simplify

TI's 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

Shrink

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 2.3mm x 2.9mm
  • Up to 40% PCB area reduction compared to discrete
