6GND
A
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.
7CS6N
A
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.
8CS6P
A
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.
9CS5P
A
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.
10
CS5N
A
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.
11
CS4N
A
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.
12
CS4P
A
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.
13
CS3P
A
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.
14
CS3N
A
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.
15
CS2N
A
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.
16
CS2P
A
Channel 2 current sense positive input. Connect through an R-C filter to
the phase-side of the channel 2 inductor.
17
CS1P
A
Channel 1 current sense positive input. Connect through an R-C filter to
the phase-side of the channel 1 inductor.
18
CS1N
A
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.
