Pin Functions

Vcom+: Positive input terminal of Vcom amplifier.

Vcom−: Negative input terminal of Vcom amplifier.

Vcom: Output terminal of Vcom amplifier.

AGND: Analog ground connection for LM2715. Connect all

sensitive circuitry, ie. feedback resistors, delay capacitor,

and compensation network to its own dedicated AGND plane

which connects directly to this pin.

Delay: PMOS switch delay control pin. See Operation sec-

tion 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

Connect resistor/capacitor network between V

C

pin and

AGND for boost switching regulator AC compensation.

FB: 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.
