Board description
12.1.1
Power input (VIN)
This is the input voltage for the power conversion. The high-side MOSFET drain is
connected to this input. Supply must be compliant with VIN recommended operating
conditions and capacitors rating.
If VIN voltage is compliant also to VCC range listed in recommended operating conditions, it
can supply also the device through R16 resistor.
12.1.2
Power iutput (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.
12.1.3
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.
12.1.4
Test points
The following test points are provided to allow easy probing of important signals:
–
COMP: output of the error amplifier;
–
FB: inverting input of the error amplifier;
–
PH: Phase pin of the device;
–
LG: Low-Side gate pin of the device;
–
UG: High-Side gate pin of the device.
