Input voltage6-36 V
Output 12.5 V / 3.5 A
IC revisionA

Description

The TPS25846Q1EVM-117 is an evaluation module (EVM) for TI's TPS25846-Q1 USB BC1.2 5-V, 3.5-A output, 36-V input synchronous buck with cable compensation. The EVM operates over a range from 6 V to 36 V and provides USB type A connectors to evaluate USB BC1.2 and USB2.0 data communication functions. The value of cable compensation, current limit, and switching frequency can be adjusted by resistors on the EVM.

Features

  • Integrated fully managed power paths
  • Integrated 5-V, 3-A, 36-mΩ sourcing switch (TPS25750S/D)
  • Integrated 28-V, 7-A, 16-mΩ bi-directional load switch (TPS25750D only)
  • Standalone USB Type-C PD solution
  • No firmware development or external micro-controller needed
  • Integrated robust power path protection
