Power trends
Power density
More power, less board space. This is the trend in applications across all markets as well as the our step-down regulator portfolio. Highlighted by the SWIFT™ buck regulator family, our portfolio of high-power density devices are highly integrated, with high performance feature sets and high output-current capability in compact, thermally-enhanced packaging.
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.

Low EMI
Mitigating buck regulator EMI can be a major challenge for many power-supply designers. Devices with built-in EMI-reduction technologies save design time while helping you comply with difficult standards such as CISPR 25 Class-5. Check out our featured step-down regulators for EMI performance.

Low noise & precision
Typical switching regulators require a post-regulator LDO to power high-resolution ADCs and AFEs. But with the industry's best noise and ripple performance, TPS62912 and TPS62913 allow you to remove that low-noise LDO in most applications, saving PCB area and overall cost while improving system efficiency.
