Power trends
Power density
More power, less board space. This is the trend in applications across all markets as well as our step-down converter portfolio. High-density buck converters are a great choice for powering high-current digital loads like FPGAs and processors.

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.
