Skip-Mode Input (SKIP)
The IC offers selectable skip-mode functionality to
reduce current consumption and achieve a higher effi-
ciency at light loads. To operate in skip mode, install a
shunt on jumper JU2. For normal operation, remove the
shunt from JU2. See Table 2 for JU2 shunt positions.
Power Good (PGOOD)
PGOOD is an open-drain output that asserts when
V
FB
is above 555mV (typ), and asserts low if V
FB
is
below 530mV (typ). On the EV kit, the PGOOD pad
is pulled up through resistor R4. The EV kit gives
the option to pull up PGOOD to the IN supply or a
user-supplied external voltage through configuration of
jumper JU3. See Table 3 for JU3 shunt positions.
