CORE
section
CS1P
Channel 1 current sense positive input.
Connect through an R-C filter to the phase-side of the channel 1 inductor. See
Section 11 for proper layout of this connection.
16
CS1N
Channel 1 current sense negative input.
Connect through a RG resistor to the output-side of the channel inductor. Filter the
Vout-side of RG resistor with 100nF to GND.
See Section 11 for proper layout of this connection.
17
CS2P
Channel 2 current sense positive input.
Connect through an R-C filter to the phase-side of the channel 2 inductor. See
Section 11 for proper layout of this connection.
18
CS2N
Channel 2 current sense negative input.
Connect through a RG resistor to the output-side of the channel inductor. Filter the
Vout-side of RG resistor with 100nF to GND.
See Section 11 for proper layout of this connection.
19
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 2 phase, directly connect to Vout_CORE.
See Section 11 for proper layout of this connection.
20
CS3N
Channel 3 current sense negative input.
Connect through a RG resistor to the output-side of the channel inductor. When
working at 2 phase, connect through RG to CS3+. Filter the Vout-side of RG resistor
with 100nF to GND.
See Section 11 for proper layout of this connection.
21
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 2 or 3 phase, directly connect to Vout_CORE.
See Section 11 for proper layout of this connection.
22
CS4N
Channel 4 current sense negative input.
Connect through a RG resistor to the output-side of the channel inductor. When
working at 2 or 3 phase, connect through RG to CS4+.Filter the Vout-side of RG
resistor with 100nF to GND.
See Section 11 for proper layout of this connection.
23
NB
section
NB_CSP
NB channel current sense positive input.
Connect through an R-C filter to the phase-side of the NB channel inductor. See
Section 11 for proper layout of this connection.
24
NB_CSN
NB channel current sense negative input.
Connect through a RG resistor to the output-side of the channel inductor. Filter the
Vout-side of RG resistor with 100nF to GND.
See Section 11 for proper layout of this connection.
