Why Portable Electronics Perform Better with SIMO PMICs

While the single inductor, multiple output (SIMO) power converter architecture has been around—at least in theory—for about 15 years, it has only recently become available in power-management ICs (PMICs) on the market. The newest iteration overcomes many of the challenges and drawbacks noted in earlier studies. In addition, the SIMO technology provides design engineers with a means to extend battery life while meeting the space-constraint demands of a variety of compact, low-power electronic designs.

What you will learn

  • How to overcome the power, efficiency, and size challenges of small, battery-powered devices as well as non-battery-powered products that need to shrink in size. To illustrate our SIMO methodology, we’ll highlight examples such as earbuds, insulin pens, and TV encrypters.

  • How the flexibility of a SIMO buck-boost converter addresses the output voltage demands of these designs without requiring discrete components

  • Why it’s important to evaluate efficiency at the full system level versus at the component level
