Power output (VOUT)
This is the output voltage of the power conversion. The output voltage is programmed to
1.25 V. It can be changed by replacing R13 (adjusting of compensation network may be
needed). Adding R18 allows to adjust OCP threshold.
IC additional supply (VCC)
The controller can be supplied separately from the power conversion through VCC input. In
this case, to separate VCC from VIN, R16 resistor must be removed.
Test points
The following test points are provided to allow easy probing of important signals:
