Texas Instruments TPSM8D6B24EVM-2V0 Power Module Evaluation Module

Texas Instruments TPSM8D6B24EVM-2V0 Power Module Evaluation Module (EVM) is configured to evaluate the operation of the TPSM8D6B24. The TPSM8D6B24 is a 4V to 16V input, dual 25A or single 50A PMBus™ power module. The input voltage range is 2.95V to 16V, and the output voltage for each 25A output is 1.8V and 3.32V. The Texas Instruments TPSM8D6B24 allows programming and monitoring via the PMBus interface.

Features

  • Regulated 1.8V and 3.32V output up to 25A DC output current (each output)
  • Convenient test points for probing critical waveforms
  • PMBus™ connector for easy connection with the TI USB adaptor

Required Equipment

  • Voltage Source
    • The input voltage source VIN must be a 0V to 18V variable DC source capable of supplying a minimum of 8ADC to support a 25A load with 5V input (or 27ADC to support a combined 50A load)
  • Oscilloscope
    • An oscilloscope is recommended for measuring output noise and ripple. Output ripple must be measured using a tip-and-barrel method
  • Output Load
    • A variable electronic load is recommended for the test setup
    • To test the full load current this evaluation module supports, the load must be capable of sinking at least 25A
  • Multimeters
    • TI recommends using two separate multimeters: one meter to measure VIN and the other to measure VOUT
  • Fan
    • During prolonged operation at high loads, it can be necessary to provide forced air cooling with a small fan aimed at the evaluation module
    • Maintain the surface temperature of the devices on the evaluation module below their rated temperature
  • USB-to-GPIO Interface Adapter
    • A communications adapter is required between the evaluation module and the host computer
    • This evaluation module is designed to use TI’s USB-to-GPIO adapter
