DC-DC converter for multiple rails with one inductor

Article By : Majeed Ahmad

Unlike other DC-DC converters that require an inductor for each rail, this IP enables SoCs to power multiple rails with just one inductor.

A new DC-DC converter IP boasts a single inductor for multiple power rails for processor cores and audio and wireless connectivity systems-on-a-chip (SoCs) serving the Internet of Things (IoT) and wearable devices. Unlike other DC-DC converter IPs that require an inductor for each rail, Vidatronic’s FlexSIMO power delivery IP enables SoCs to power multiple rails with just one inductor.

That leads to significant power and area savings for chips in IoT and wearable designs. Moises Robinson, president and co-founder of Vidatronic, said that the need for multiple rails for different functions has risen significantly in modern SoCs serving battery-powered systems like wearables and IoT devices. “The single-inductor multiple-output DC-DC converter technology is optimized to provide power supplies for the next generation of processors and audio and wireless connectivity SoCs for IoT and wearable devices.”

The DC-DC converter IPs also offer on-demand power delivery with high efficiency across all load levels and output settings with a scalable number of outputs mixed between buck, boost, and floating output configurations.

Vidatronic claims that its FlexSIMO IP has already been licensed to several customers. Though it’s currently available in 180-nm and 22-nm processes, Vidatronic says that its DC-DC converter IP can be ported to any process a customer requires.
