The power architectures of modern industrial and consumer products are liberally sprinkled with DC-DC converters, offering point-of-load regulation for various circuit subsystems. Even in products with a front-end AC-DC converter, the power system requires multiple DC-DC converters to post-regulate and provide the correct voltage and current to the output circuits. That is, until now.

A new power converter architecture challenges the dominance of output boost and buck converters and, in some cases, even the modest linear regulators that currently proliferate. Based around a novel AC-DC flyback topology employed by the InnoSwitchâ„¢3-MX and InnoMuxâ„¢ chipset from Power Integrations (PI), this new technology delivers a single-stage converter with multiple independently-regulated outputs from a single magnetic component, eliminating the need for DC-DC post-regulation and therefore dramatically increasing system efficiency.
