Step-down (Buck)

Because DC/DC step-down (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.

Step-up (Boost)

Our low-power boost converters support your need for small solution size, low system cost and high power density.

Buck-boost, inverting & split rail

Our buck-boost, inverting and split-rail converters integrate FETs to reduce component count in your system and simplify your board design.

Isolated

Easily generate one or more isolated positive and negative supplies using a small number of external components. An optocoupler is not required, and devices can be used for isolated applications.

Charge pumps (inductorless)

Our easy-to-use charge pumps offer the industry's smallest solution size and highest performance. They are ideal for low-power industrial, personal electronics and telecommunications applications.

Expand functionality in automotive infotainment and cluster systems with TI buck converters and controllers

Today's automotive infotainment and cluster systems inform, entertain, and connect modern drivers. As we look to the future, the amount of functionality within these systems is only expected to increase. This means more processing power within the same physical space. In order to power these next-generation systems, power converters need to excel in two key aspects. 

  • High output power-to-package size ratio without overheating.
  • Minimized conducted and radiated electromagnetic interference.
