C
FBG
Remote ground sense.
Connect to the negative side of the load for remote sensing. See
Section 9
for proper layout of this connection.
8
OS
Offset programming pin.
Internally set to 1.24V. Connecting a R
OS
resistor to SGND allows to set
a current that is mirrored into FB pin in order to program a positive off-
set according to the selected R
FB
.
Short to SGND to disable the function. See
Section 6.4
for details.
9
LTB
LTB Technology
TM
Input pin.
Connect through an R
LTB
- C
LTB
network to the regulated voltage
(CORE Section) to detect load transient. See
Section 10
for details.
10
OVP / V_FIX
OVP.
Over Voltage Programming Pin. Internally pulled-up to 3.3V by
11
μ
A. Connect to SGND through a R
OVP
resistor and filter with 10nF
(typ) to set a fixed voltage according to the R
OVP
resistor. If floating it
will program 3.3V threshold. See
Section 7
for details.
V_FIX - Hardware override.
Short to SGND to enter VFIX mode
(WARNING: this condition overrides any code programmed on the VIDx
lines). In this case, the device will use SVI inputs as static VIDs and
OVP threshold will be set to 1.8V. See
Section 5.4.5
for details.
11
C
S
LTB_GAIN
LTB Technology
TM
gain pin.
Connect to SGND through a resistor R
LTBGAIN
to program the LTB
Gain. See
Section 10
for details.
12
PSI_L
Power Saving Indicator (SVI Mode).
Open-drain Input/Output pin. See
Section 5.4.3
for details.
13
C
CS1+
Channel 1 Current Sense Positive Input. Connect through an R-C filter
to the phase-side of the channel 1 inductor.
See
Section 9
for proper layout of this connection.
14
CS1-
Channel 1 Current Sense Negative Input. Connect through a R
G
resis-
tor to the output-side of the channel inductor.
See
Section 9
for proper layout of this connection.
15
CS2+
Channel 2 Current Sense Positive Input. Connect through an R-C filter
to the phase-side of the channel 2 inductor.
See
Section 9
for proper layout of this connection.
16
CS2-
Channel 2 Current Sense Negative Input. Connect through a R
G
resis-
tor to the output-side of the channel inductor.
See
Section 9
for proper layout of this connection.
17
CS3+
Channel 3 Current Sense Positive Input. Connect through an R-C filter
to the phase-side of the channel 3 inductor. When working at 2 phase,
directly connect to V
out_CORE
.
See
Section 9
for proper layout of this connection.
18
CS3-
Channel 3 Current Sense Negative Input. Connect through a R
G
resis-
tor to the output-side of the channel inductor. When working at 2 phase,
connect through R
G
to CS3+.
See
Section 9
for proper layout of this connection.
