NAME

FBDC1
FUNCTION
Positive Current-Sense Input for SMPS1. Connect to the positive side of the output current-sensing
resistor or the filtering capacitor if the DC resistance of the output inductor is utilized for current
sensing.
Negative Current-Sense Input for SMPS1. Connect to the negative side of the output current-sensing
resistor or the filtering capacitor if the DC resistance of the output inductor is utilized for current
sensing.
A 20
discharge FET is enabled from CSN1 to PGND when the SMPS1 is shut down.
Feedback Sense Input for SMPS1. Connect a resistor R FBDC1 between FBDC1 and the positive side
of the feedback remote sense, and a capacitor from FBAC1 to couple the AC ripple from FBAC1 to
FBDC1. An integrator on FBDC1 corrects for output ripple and ground-sense offset.
To enable a DC load-line less than the AC load-line, add a resistor from FBAC1 to FBDC1.
To enable a DC load-line equal to the AC load-line, short FBAC1 to FBDC1. See the Core Steady-
State Voltage Positioning (DC Droop) section.
FBDC1 is high impedance in shutdown.
Output of the AC Voltage-Positioning Transconductance Amplifier for SMPS1. The R and C network
between this pin and the positive side of the remote-sensed output voltage sets the transient AC
droop:

FBAC1
R DROOP_AC1 =
R FBDC1 × R FBAC1
R FBDC1 + R FBAC1 + R FB11 Z CFB 1
x R SENSE1 x Gm (FBAC1)
where R DROOP_AC1 is the transient (AC) voltage-positioning slope that provides an acceptable
trade-off between stability and load-transient response, Gm (FBAC1) = 2mS (typ), R SENSE1 is the
value of the current-sense element that is used to provide the (CSP1, CSN1) current-sense voltage,
and Z CFB1 is the impedance of C FB1 .
FBAC1 is high impedance in shutdown.
SMPS1 Remote Ground-Sense Input. Normally connected to GND directly at the load. GNDS1
internally connects to a transconductance amplifier that fine tunes the output voltage—
37
GNDS1
compensating for voltage drops from the SMPS ground to the load ground.
Connect GNDS1 or GNDS2 above 0.9V combined-mode operation (unified core). When GNDS1 is
pulled above 0.9V, GNDS2 is used as the remote ground-sense input.
