Table 3-1. EVM Board Connections
Test Point 5001 5002 5003 5004 Connection Description
TP1, J1
✓ ✓ ✓ ✓
OUTA
Connected to the gate driver in the design.
Components R5, C5 can be used to test
different R/C loads.
TP2, J2
✓ ✓
OUTB
Connected to the gate driver in the design.
Components R6, C6 can be used to test
different R/C loads.
TP3, J3
✓ ✓ ✓
SRA
Connected to the gate driver in the design.
Components R7, C7 can be used to test
different R/C loads.
TP4, J4
✓
SRB
Connected to the gate driver in the design.
Components R8, C8 can be used to test
different R/C loads.
TP5, TP6
✓ ✓ ✓ ✓
CS_LIM
Input for current sense in the design.
The CS_LIM circuit provides small triangle
waveform from OUTA, OUTB. Note that
this can load OUTA, OUTB causing a
slow in the slew rate. If R9 and R10 are
unpopulated, CS_LIM can be force from
TP5.
TP7

VIN
Voltage input for the
TPS7H5001/2/3/4EVM-CVAL device
TP8
✓ ✓ ✓ ✓
EN
Enable pin for the TPS7H5001/2/3/4EVM-
CVAL device, currently pulled high to VLDO
TP9
✓ ✓ ✓ ✓
COMP
Error amplifier output for the
TPS7H5001/2/3/4EVM-CVAL, forcing this
voltage runs the TPS7H5001/2/3/4EVM-
CVAL in open loop.
TP10
✓ ✓ ✓ ✓
REFCAP
Internal reference for
TPS7H5001/2/3/4EVM-CVAL
TP11, TP12
✓ ✓ ✓ ✓
SS
In a closed loop design, this slowly
increases converter output voltage during
start-up
TP13, TP15
✓ ✓ ✓ ✓
SYNC
Inputting a clock on this pin synchronizes
the TPS7H5001/2/3/4EVM-CVAL to a
frequency half of the input frequency
TP14
✓ ✓ ✓ ✓
VLDO Internal voltage rail for device logic
TP20
✓ ✓ ✓ ✓
VSENSE
Voltage sense for the
TPS7H5001/2/3/4EVM-CVAL. Connected
to converter output voltage in the full
design.
TP21
✓ ✓ ✓ ✓
RSC
Slope compensation selection resistor. Sets
slope compensation slew rate internal to
the device.
