Quick start
1.
Connect the VIN+ and VIN- test points of the evaluation board to an external power
supply.
2.
Ensure that all DIP switches (S2) are in the "OFF" position. In this condition all outputs
are disabled (shutdown mode).
3.
Turn S21 to the “ON” position (SHDN pin high). This turns on the LDO5 output
(standby-mode).
4.
Turn S22 to the “ON” position (EN1 pin high). The 1.5 V switching controller begins
regulation of the output. PGOOD1 pin goes high after soft-start.
5.
Turn S23 to the “ON” position (EN2 pin high). The 1.05 V switching controller begins
regulation of the output. PGOOD2 pin goes high after soft-start.
6.
In order to load the switching outputs, the loads must be connected between the "+"
and the "-" output test points, respectively.
7.
In order to load the linear outputs, the loads must be connected between J10 and
LDO5 or alternative RLD5V resistors can be used on the evaluation board.
