5V@2.1A USB Charger Automotive Reference Design

PMP10282

Design files

Overview

This USB 3.0 charger provides 5V @ 2.1A over an automotive input range of 8V - 40V. It uses the integrated FET TPS54340 PWM Buck controller and implements cable voltage droop compensation. A TPS2546 charging port controller provides data line switching plus an integrated FET with dual current protection thresholds.

Features
  • 8 to 40V (12V nominal) input voltage and 5V/2.1A output with TPS54340
  • Programmable voltage droop
  • Supports both USB 2.0 and 3.0 power switch requirements
  • This reference design has been lab tested and is supported with design files and an application note
