Dual Battery Charger IC Reference Design (connected in Cascode Configuration)


Design files


Higher capacity 1S batteries in the latest smartphones and tablets need higher charge currents to charge faster.  With 12-V power sources, two 5-A battery charger ICs connected in cascode, parallel configuration can provide more than 5-A charging current.  In addition, the heat from the charger's power losses are distributed across your PCB.

  • Fast charge a smartphone on PCB with low thermal budget
  • Charge currents > 5 A from 12-V supply
  • This circuit design is tested and uses the EVM GUI and getting started guide
