Overview

PMP11114 is a dual port USB Type C Charger. This design takes an automotive input voltage (7V to 18V nominal, load dump to 40V).  The output goes to two USB Type ports, each of these ports supplies 5V.  The desgin supports 3A on one port and 1.5A on the other port.  The DC/DC portion of the design is rated for 5A total current.  The design is fully compliant with USB type C and backwards compliant with BC1.2 and DCP configurations.

Features
  • USB Type C compliant
  • Efficiency is greater than 90% after USB switches
  • Max component temp is 55C with full load
  • Compact board size (50mm x 55mm)
  • Power path sharing to limit port current
