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 synchroniza-
tion. Clock edges should have rise and fall times faster
than 1μs. See Synchronization 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.

pin fl oating.
ADJ (Pin J7): The LTM8031 regulates its ADJ pin to 0.79V.
