We'll explore how the new DC/DC power modules in the Texas Instruments (TI) TPSM8281x family of power modules help simplify power solutions by minimizing design complexity and extending battery life in industrial applications.

DC/DC power modules are compact, integrated devices that convert an input DC voltage level to another voltage level. In addition to efficient power conversion, these small power solutions offer a variety of advantages, including a stable, regulated output voltage for sensitive electronics, a compact size for space-constrained or printed circuit board (PCB) space-constrained applications, and design versatility that enables them to handle a variety of input voltages and convert them to the desired output level. Together, these advantages make DC/DC power modules suitable for a wide range of applications.


Different types of power supplies and connectors mean different types of DC/DC power modules. The most common of these include:

-Buck Converter Modules: Also known as buck converters, these modules reduce the input voltage to a lower, stabilized output voltage.

-Boost Converter Modules: Also known as boost converters, these raise the input voltage to a higher, stabilized output voltage.

-Buck-Boost Converter Modules: These modules boost or buck the input voltage to maintain a constant output voltage independent of input fluctuations.
