PIN FUNCTIONS
R ADJ =
SYNC(PinL6): Thisistheexternalclocksynchronization
input. Ground this pin for low ripple Burst Mode ? operation
at low output loads. Tie to a stable voltage source greater
than 0.7V to disable Burst Mode operation. Do not leave
this pin floating. 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 final regulation voltage.
BLOCK DIAGRAM
FIN
The PGOOD output is valid when V IN is above 3.6V and
RUN/SS is high. If this function is not used, leave this
pin floating.
ADJ (Pin J7): The LTM8031 regulates its ADJ pin to 0.79V.
Connect the adjust resistor from this pin to ground. The
value of R ADJ is given by the equation:
196.71
V OUT – 0.79
where R ADJ is in kΩ.
