2.1 Power Requirements

This EVM comes populated with a TPS7B84-Q1 LDO to provide a DC reference voltage to the tracker LDO if the user does not have an external supply to provide the reference voltage. The power supply requirement for the TPS7B84-Q1 depends on the output voltage setting chosen with J15; a 10-V, 100-mA current limit supply covers all of the default output voltage settings for the on-board TPS7B84-Q1. This supply is the same as the input supply for the tracker LDO.

This EVM also includes an on-board load transient circuit that is driven by the LM1020 gate driver. The LM1020 requires a nominal 5 V supply that must not exceed 5.4V and must be no less than 4.75V.
