Overview

PMP9402 is a dual USB car charger. This design utilizes the LM3150, TPS2561 Dual Channel Power Switch and a TPS2513 USB Dedicated Charging Port Controller. This design operates from 6 to 40V in. The output is set to 5V; both channels have a 2.5A current limit. This design has a switching frequency of 300 kHz. This design is intended for after-market automotive applications.

Features
  • Dual USB charger complete system design, 12.5W output each
  • 2.5A current limit protection for each channel by TPS2561 power switch
  • Compact solution size: 990mm²
  • Wide Vin range 6V to 40V, suitable for 12V car battery input
  • Constant On-Time controller, no loop compensation required, fast transient response
