This Reference-Design is to power the USB port that aims to supports Quick Charge 2.0 from one cell li-ion Battery or a Power supply between 2.7V and 4.4V. It consists of a boost converter TPS61088 supporting up to 12V output, a 12 E-fuse TPS2592AA for short circuit protection and a charger interface IC CHY100 to adjust output voltage according the Quick Charge 2.0 standard. It can support 5V&3A, 9V&2A and 12V&1.5A output power.


  • Support Quick Charge 2.0 Class A
  • Up to 18 Watts Output Power
  • One Cell Li-ion Battery Input
  • The circuit is tested on a 38mm*15mm Evaluation Board
