High Current, Inductor-less Power Converter with Power Efficiency Above 98

The DA9313 integrates the industry’s first inductor-less 10A power converter for best-in-class efficiency and offers master/slave operation for up to 20A of output current. The high current, inductor-less power converter offers incredible efficiency above 98%, powering greater than 50W in a less than 10mm2 package.

DA9313 enables applications to be powered with improved efficiencies and requires less volume compared to conventional high voltage direct conversion solutions. The fully integrated power converter halves the input voltage without the requirement for inductors and provides flat efficiency over a very wide range of output current.

Today’s competitor devices using charge pump technology to generate a regulated output voltage and have very limited output current capabilities.

Benefits

* 10A total output current from 5.0V to 10.5V * Master/Slave configuration for up to 20A output current * Enabling low profile externals (z-height ≤1mm) for high current application * Solution size reduction in comparison to inductor based solutions * Thermal hotspot reduction through ultra-high efficiency (98%)
