LTM8023
PIN FUNCTIONS
V IN (Bank 1): The V IN pin supplies current to the LTM8023’s
internal regulator and to the internal power switch. This
pin must be locally bypassed with an external, low ESR
capacitor of at least 2.2μF.
V OUT (Bank 2): Power Output Pins. Apply the output filter
capacitor and the output load between these pins and
GND pins.
AUX (Pin F5): Low Current Voltage Source for BIAS. The
V AUX pin is internally connected to V OUT and is placed
adjacent to the BIAS pin to ease printed circuit board
routing. Although this pin is internally connected to V OUT ,
do NOT connect this pin to the load. If this pin is not tied
to BIAS, leave it floating.
BIAS (Pin G5): The BIAS pin connects to the internal power
bus. Connect to a power source greater than 2.8V. If the
output is greater than 2.8V, connect this pin there. If the
output voltage is less, connect this to a voltage source
between 2.8V and 16V. Also, make sure that BIAS + V IN
is less than 56V.
RUN/SS (Pin H5): Tie RUN/SS pin to ground to shut down
the LTM8023. Tie to 2.5V or more for normal operation.
If the shutdown feature is not used, tie this pin to the V IN
pin. RUN/SS also provides a soft-start function; see the
Applications Information section.
GND (Bank 3): Tie these GND pins to a local ground plane
below the LTM8023 and the circuit components. In most
applications, the bulk of the heat flow out of the LTM8023
is through these pads, so the printed circuit design has a
large impact on the thermal performance of the part. See
the PCB Layout and Thermal Consideration sections for
more details. Return the feedback divider (R ADJ ) to this net.
R T (Pin G7): The R T pin is used to program the switching
frequency of the LTM8023 by connecting a resistor from
this pin to ground. The Applications Information section of
the data sheet includes a table to determine the resistance
value based on the desired switching frequency. Minimize
capacitance at this pin.
SHARE (Pin F7): Tie this to the SHARE pin of another
LTM8023 when paralleling the outputs. Otherwise, do not
connect (leave floating).
SYNC (Pin G6): This is the external clock synchronization
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 synchronization.
Clock edges should have rise and fall times faster than 1μs.
See synchronizing section in Applications Information.
PGOOD (Pin H6): The PGOOD pin is the open-collector
output of an internal comparator. PG remains low until
the ADJ pin is within 10% of the final regulation voltage.
PG 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 H7): The LTM8023 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 R ADJ = 394.21/
(V OUT – 0.79), where R ADJ is in kΩ.
