DC/DC buck converters

Balancing simplicity with flexibility

Because buck converters feature a controller with one or more integrated FETs and an external inductor, they offer a balance of flexibility and ease of use. Both non-synchronous converters (integrated high-side FET and external inductor) and synchronous converters (integrated high-side AND low-side FETs) simplify the design process by reducing external component count.

At the same time, an external inductor allows you the flexibility to optimize your power supply for efficiency, size, or cost. No matter what your application is, TI has a DC/DC buck converter and design tools to help you address your power supply design challenges.


DC/DC buck converter ICs intended to take input voltages from various battery chemistries.

3.3 V & 5 V

3.3 V and 5 V are common intermediate buses and are also popular input rails for personal electronics and other low-power systems.

12 V

DC/DC step-down converters for common 12V input applications like communications infrastructure, enterprise computing, or 12V automotive systems.

24 V

DC/DC buck converters targeting a nominal 24V input, with maximum operating input voltages as high as 100V to protect against voltage transients. Common application areas needing 24V are broad industrial and 24V automotive.

48 V

DC/DC step-down converters for nominal 48V input voltage systems like telecommunications infrastructure and the emerging HEV/EV automotive space.
