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.

Power trends
Power density
More power, less board space. In addition to being a trend in applications across all markets, it is also one of the key benefits of using a step-down module. Buck modules feature an integrated inductor and FETs to not only minimize power supply size, but also simplify design and help get customers to market faster. On the inside, the centerpiece of each module is a high-efficiency buck regulator surrounded by a layout optimized for thermal performance.
High-density power modules are a great choice for powering high-current digital loads like FPGAs and processors. Use our processor-attach tool to find the best power supply devices to surround your FPGA or processor.

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.
