PMP5225 TPS51116 with 2xCSD16406Q3 Test Report Texas Instruments


PMP5225 Test report:

Testing focus was on the switching regulator, not the 0.75V linear regulator which was
copied from previous EVMs. When the linear regulator dissipates more than 1 watt or its
steady state current is more than 1.3A source or sink; airflow will be needed with this
EVM.
