Figure 1, must remain unpopulated under all cases. When evaluating the LM5160A, the designer needs to use the same standard EVM by replacing the LM5160 IC (when/if populated) with the LM5160A. No other components on board need to be replaced or removed. With LM5160A IC, the designer can use other nominal output voltage (V... -
