Pins description and connection diagrams
L6711
8/50
8FB
This pin is connected to the error amplifier inverting input and is used to compensate the
voltage control feedback loop.
Connecting a resistor between this pin and VSEN pin allows programming the droop effect.
9OVP
Over Voltage protection setup pin: it allows programming the OVP intervention.
Internally pulled-up to 5V, it sources a constant 12.5
A current.
Leaving the pin floating the OVP threshold is set to 115% (Typ.) of the programmed voltage
Connecting a resistor ROVP to SGND, it sets the OVP threshold to a fixed programmable
voltage (see relevant section for further details). Filter with 10nF vs. SGND in this case.
10
VSEN
Manages Over&Under-voltage conditions. It is internally connected with the output of the
Remote Sense Buffer for Remote Sense of the regulated voltage.
If no Remote Sense is implemented, connect it directly to the regulated voltage in order to
manage OVP and UVP.
11
FBR
Remote sense buffer non-inverting input.
It has to be connected to the positive side of the load to perform a remote sense.
12
FBG
Remote sense buffer inverting input.
It has to be connected to the negative side of the load to perform a remote sense.
13
OUTEN
Output Enable pin; internally 3V pulled-up, it can be pulled-up with a resistor up to 3.3V.
If forced to a voltage lower than 0.3V, the device stops operation with all mosfets OFF: all the
protections are disabled in this condition except pre-OVP.
Cycle this pin to recover latch from protections; filter with 1nF (Typ.) capacitor vs. SGND.
14
CS1-
Channel 1 Current Sense Negative Input pin.
It must be connected through an Rg resistor to the LS mosfet drain (or to the LS-side of the
sense resistor placed in series to the LS mosfet) if LS mosfet sense is performed
(CS_SEL=OPEN). Otherwise (CS_SEL=SGND), it must be connected to the output-side of
the output inductor (or the output-side of the sense resistor used and placed between the
channel 1 inductor and the output of the converter) through Rg resistor.
The net connecting the pin to the sense point must be routed as close as possible to the CS1+
net in order to couple in common mode any picked-up noise.
15
CS1+
Channel 1 Current Sense Positive Input pin.
It must be connected through an Rg resistor to the LS mosfet source (or to the GND-side of
the sense resistor placed in series to the LS mosfet) if LS mosfet sense is performed
(CS_SEL=OPEN). Otherwise (CS_SEL=SGND), it must be connected to the phase-side of
the output inductor (or the inductor-side of the sense resistor used and placed between the
channel 1 inductor and the output of the converter) through Rg resistor and an R-C network
across the inductor.
The net connecting the pin to the sense point must be routed as close as possible to the CS1-
net in order to couple in common mode any picked-up noise.
16
CS2-
Channel 2 Current Sense Negative Input pin.
It must be connected through an Rg resistor to the LS mosfet drain (or to the LS-side of the
sense resistor placed in series to the LS mosfet) if LS mosfet sense is performed
(CS_SEL=OPEN). Otherwise (CS_SEL=SGND), it must be connected to the output-side of
the output inductor (or the output-side of the sense resistor used and placed between the
channel 2 inductor and the output of the converter) through Rg resistor.
The net connecting the pin to the sense point must be routed as close as possible to the CS2+
net in order to couple in common mode any picked-up noise.
