The TPSM846C23DEVM-807 evaluation module (EVM) is configured to evaluate the parallel operation of the TPSM846C23 PMBus power module for output currents up to 70 A. The input voltage range is 4.5 V to 15 V, with an output voltage range of 0.35 V to 2.0 V. The EVM’s PMBus interface allows power supply configuration as well as monitoring of key parameters, including output voltage, output current, and the internal die temperature, as well as many user programmable configuration options. The EVM has several test points and jumpers to easily evaluate the TPSM846C23 parallel operation.

The EVM includes a PMBus connector to interface with a host PC. The USB-to-GPIO interface adapter pod is required to program the EVM. The USB-to-GPIO interface pod connects the EVM to a computer USB port which allows the TI “Fusion” Graphical User Interface (GUI) to communicate and control the EVM.

The TPSM846C23DEVM-807 can be ordered separately or as part of a bundle with the USB-to-GPIO interface adapter pod.

  • 4.5V to 15V Input Voltage Range
