Remote sense buffer non-inverting input.
It has to be connected to the positive side of the load to perform a remote sense.
Remote sense buffer inverting input.
It has to be connected to the negative side of the load to perform a remote sense.
Output Enable pin, internally 3V pulled-up.
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.
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.
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.
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.
Channel 2 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
2 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 CS2-
net in order to couple in common mode any picked-up noise.
Channel 3 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 3
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 CS3+
net in order to couple in common mode any picked-up noise.
