Board description
13.1.1
Power input (Vin)
This is the input voltage for the power conversion. The high-side drain is connected to this
input. This voltage can range from 1.5 V to 12 V bus.
If the voltage is between 4.5 V and 12 V, it can also supply the device (through the Vcc pin),
and in this case the R16 (0
Ω) resistor must be present.
13.1.2
Output (Vout)
The output voltage is fixed at 1.25 V, but can be changed by replacing resistors R8 (sense
partition lower resistor) and R13 (feedback partition lower resistor). R18 allows the
adjustment of the OCP threshold.
13.1.3
Signal input (Vcc)
When using the input voltage Vin to supply the controller, no power is required at this input.
However, the controller can be supplied separately from the power stage through the Vcc
input (4.5-12 V) and, in this case, the R16 (0
Ω) resistor must be unsoldered.
13.1.4
Test points
Several test points are provided for easy access to all the important signals that characterize
the device:
–
COMP: The output of the error amplifier
–
FB: The inverting input of the error amplifier
–
PGOOD: Signaling regular functioning (active high)
–
VGDHS: The bootstrap diode anode
–
PHASE: Phase node
–
LGATE: Low-side gate pin of the device
–
HGATE: High-side gate pin of the device
