GND

GND connection. All internal references and logic are referenced to this pin.

Filter to VCC5 with proper MLCC capacitor and connect to the PCB GND

plane.

CS6N

Channel 6 current sense negative input. Connect through an Rg resistor to the

output-side of the channel inductor. When working at < 6 phases, still connect

through Rg to CS6P and then to the regulated voltage. Filter the output-side of

Rg with 100 nF (typ) to GND.

CS6P

Channel 6 current sense positive input. Connect through an R-C filter to the

phase-side of the channel 6 inductor. When working at < 6 phases, short to

the regulated voltage.

CS5P

Channel 5 current sense positive input. Connect through an R-C filter to the

phase-side of the channel 5 inductor. When working at < 5 phases, short to

the regulated voltage.

CS5N

Channel 5 current sense negative input. Connect through an Rg resistor to the

output-side of the channel inductor. When working at < 5 phases, still connect

through Rg to CS5P and then to the regulated voltage. Filter the output-side of

Rg with 100 nF (typ.) to GND.

CS4N

Channel 4 current sense negative input. Connect through an Rg resistor to the

output-side of the channel inductor. When working at < 4 phases, still connect

through Rg to CS4P and then to the regulated voltage. Filter the output-side of

Rg with 100 nF (typ.) to GND.

CS4P

Channel 4 current sense positive input. Connect through an R-C filter to the

phase-side of the channel 4 inductor. When working at < 4 phases, short to

the regulated voltage.

CS3P

Channel 3 current sense positive input. Connect through an R-C filter to the

phase-side of the channel 3 inductor. When working at < 3 phases, short to

the regulated voltage.

CS3N

Channel 3 current sense negative input. Connect through an Rg resistor to the

output-side of the channel inductor. When working at < 3 phases, still connect

through Rg to CS3P and then to the regulated voltage. Filter the output-side of

Rg with 100 nF (typ.) to GND.

CS2N

Channel 2 current sense negative input. Connect through an Rg resistor to the

output-side of the channel inductor. Filter the output-side of Rg with 100 nF

(typ.) to GND.

CS2P

Channel 2 current sense positive input. Connect through an R-C filter to the

phase-side of the channel 2 inductor.

CS1P

Channel 1 current sense positive input. Connect through an R-C filter to the

phase-side of the channel 1 inductor.

CS1N

Channel 1 current sense negative input. Connect through an Rg resistor to the

output-side of the channel inductor. Filter the output-side of Rg with 100 nF

(typ.) to GND.
