Pin Functions
Vcom+(Pin 1):
Positive input terminal of Vcom amplifier.
Vcom(Pin 2):
Negative input terminal of Vcom amplifier.
Vcom(Pin 3)
: Output terminal of Vcom amplifier.
AGND(Pin 4):
Analog ground connection for LM2715. Con-
nect all sensitive circuitry, ie. feedback resistors, delay ca-
pacitor, and compensation network to its own dedicated
AGND plane which connects directly to this pin.
Delay(Pin 5):
PMOS switch delay control pin. See
Operation
section for setting the delay time.
The delay time begins when the output voltage of the DC/DC
switching regulator reaches 85% of its true output voltage.
This corresponds to a FB voltage of about 1.1V. The PMOS
switch is controlled with both the delay time and the switch
control pin, SWC. If no Cdelay capacitor is used, the PMOS
switch is controlled solely with the SWC pin.
V
(Pin 6):
Compensation Network for Boost switching regu-
lator. Connect resistor/capacitor network between V
pin
and AGND for boost switching regulator AC compensation.
FB(Pin 7):
Feedback pin. Set the output voltage by selecting
values of R1 and R2 using:
Connect the ground of the feedback network to the AGND
plane, which should be tied directly to the PGND pin.
Ordering Information
PGND(Pin 8):
Connect all power ground components to a
PGND plane which should also connect directly to this pin.
Use a trace or via to connect the AGND plane to the PGND
plane. Please see Layout Considerations under the Opera-
tion section for more details on layout suggestions.
SW(Pin 9):
This is the drain of the internal NMOS power
switch. Minimize the metal trace area connected to this pin to
minimize EMI.
V
IN
(Pin 10):
Input Supply Pin. Bypass this pin with a capaci-
tor as close to the device as possible. The capacitor should
connect between V
IN
and PGND.
SWI(Pin 11):
PMOS switch input. Source connection of
PMOS device.
SWO(Pin 12):
PMOS switch output. Drain connection of
PMOS device.
SWC(Pin13):
PMOS switch control pin. This pin creates an
AND function with the delay time after the output of the
switching regulator has reached 85% of its nominal value. To
ensure the PMOS switch is in the correct state, apply a
voltage above 1.5V to this pin to turn on the PMOS switch
and apply a voltage below 0.7V to turn off the PMOS switch.
AV
(Pin 14):
Supply pin for the Vcom opamp and the
Gamma buffer. Bypass this pin with a capacitor as close to
the device as possible, about 100nF, if connected directly to
the output of the boost DC/DC switching regulator. The
capacitor should connect between AV
IN
and PGND.
GMA(Pin 15):
Gamma Buffer output pin.
GMA+(Pin 16):
Gamma Buffer input pin.
