Expected Values
and
outline the expected values for certain test points on the board to monitor the
functionality of the TSW2110. Depending on the input voltage configuration on the board, some of the
expected values are different. The charge pump draws more current in the 3.3-V input configuration than
the LDO regulator does with the 5-V input.
