Texas Instruments TPS25846Q1EVM-117 Evaluation Module

Texas Instruments TPS25846Q1EVM-117 Evaluation Module is designed to quickly and easily demonstrate the TPS25846-Q1 Synchronous Buck Converter with cable compensation. The TPS25846-Q1 USB BC1.2 5V, 3.5A output, 36V input synchronous buck Converter offers cable droop compensation, resulting in the Vbus voltage remaining constant regardless of load current, ensuring connected portable devices are charged at optimal current and voltage even under heavy loads.

The TI TPS25846Q1EVM-117 Evaluation Module operates over a range from 6V to 36V and provides USB type-A connectors to evaluate USB BC1.2 and USB2.0 data communication functions. Resistors can adjust the value of cable compensation, current limit, and switching frequency on the TPS25846Q1EVM-117 Evaluation Module.

Features

  • 6V to 36V input range, 3.5A continuous output current buck converter
  • Forced PWM operation with spread-spectrum dithering
  • Fully AEC-Q100 qualified
