Description

The PMP10885 reference design is capable of charging two devices simultaneously at 2.4A each. The UCC24636 synchronous rectifier controller and CSD18531Q5A FET reduce the rectifier loss and provide high efficiency with a minimal increase in cost.  The TPS2559 provides accurate and independent current limit protection for each port. The TPS2513 communicates with the mobile device under charge to ensure that the charger is accepted by most phone and tablet models. This compact design consumes a volume of only 1.3" x 2.4" x 0.9".

Features
  • High 4-point average efficiency (>85% AC/DC only; >84% end-to-end)
  • Compact size and high power density (8.5W/in^3)
  • Conducted emissions below Class B limits
