PIN FUNCTIONS
SYNC (Pin L6): This is the external clock synchronization
input. Ground this pin for low ripple Burst Mode
at low output loads. Tie to a stable voltage source greater
than 0.7V to disable Burst Mode operation. Do not leave
this pin fl oating. Tie to a clock source for synchronization.
Clock edges should have rise and fall times faster than 1μs.
See synchronizing section in Applications Information.
PGOOD (Pin K7): The PGOOD pin is the open-collector
output of an internal comparator. PGOOD remains low until
the ADJ pin is within 10% of the fi nal regulation voltage.
The PGOOD output is valid when V
RUN/SS is high. If this function is not used, leave this
pin fl oating.
