13.1.2
Output (Vout)
The output voltage is fixed at 1.25V but it can be changed by replacing the resistors R8
(sense partition lower resistor ) and R13 (feedback partition lower resistor). The over-
current-protection limit is set at 15A but it can be changed by replacing the resistors R18.
13.1.3
Signal input (Vcc)
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 (4.5-12V) and, in this case, the R16 (0Ohm) resistor must be unsoldered.
13.1.4
Test points
Several test points are provided to have easy access at all important signal characterizing
the device:
–
COMP: the output of the error amplifier;
–
FB: the inverting input of the error amplifier;
–
PGOOD: signaling the 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.
