Description

PMP9367 is a dual USB car charger reference design intended for use in aftermarket automotive application. 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 outputs is set to 5V, channel one has a 1A current limit and channel two has a 2.1A current limit. This design has a switching frequency of 300 kHz.

Features
  • Small overall solution size.
  • +5V/3.5A with LM3150 capable of 6V to 40V input
  • Synchronous Controller provides 95% peak efficiency
  • Constant On Time Control, No Loop Compensation Required, and Fast Transient Response
  • Emulated Ripple Mode (ERM) control allows for the use of low ESR output capacitors.
