Programming the Current-Limit
The Current-Limit threshold can be set by
connecting a resistor (R
OCSET) from the SW pin
to the OCSet pin. The resistor can be calculated
by using equation (4). This resistor R
OCSET must
be placed close to the IC.
The
R
DS(on)
has
a
positive
temperature
coefficient and it should be considered for the
worst case operation.
Setting the Power Good Threshold
A window comparator internally sets a lower
Power Good threshold at 85% of Vp and an
upper Power Good threshold at 115% of Vp.
When the voltage at the FB pin is within the
window set by these thresholds, PGood is
asserted.
The PGood is an open drain output. Hence, it is
necessary to use a pull up resistor R
PG from
PGood pin to Vcc.
The value of the pull-up
resistor must be chosen such as to limit the
current flowing into the PGood pin, when the
output voltage is not in regulation, to less than 5
mA. A typical value used is 4.7kΩ.
