Description
J14
EVM 5V input voltage (VIN). Use with GND at J16 and with JP1 set to the VIN position.
J16
EVM input GND used with J14 (VIN).
J3
Negative supply input used with J3 (GND). Set J4 shunt to the NEGVDC SNS4H position to monitor negative
supplies using SENSE4H.
supplies using SENSE4H.
J1
GND input used with J3 (NEGVDC).
J13
TPS65055 DCDC1 output voltage (VDCDC1) which is nominally 2.1VDC.
J15
GND output used with J13 (VDCDC1).
J17
TPS65055 DCDC2 output voltage (VDCDC2) which is nominally 1.0VDC.
J18
GND output used with J17 (VDCDC2).
J19
TPS65055 LDO1 output voltage (VLDO1) which is nominally 1.2VDC.
J21
GND output used with J19 (VLDO1).
J23
TPS65055 LDO2 output voltage (VLDO2) which is nominally 1.8VDC.
J25
GND output used with J23 (VLDO2).
J27
TPS65055 LDO3 output voltage (VLDO3) which is nominally 2.8VDC.
J29
GND output used with J27 (VLDO3).
J30
TPS65055 LDO4 output voltage (VLDO4) which is nominally 1.3VDC.
J32
GND output used with J30 (VLDO4).
J33
Used with the USB-GPIO adapter for communication with the TPS65055 using the TPS65055 GUI. The USB-GPIO
adapter can also provide 3.3V to the EVM (derived from the PC on which the GUI is operating) when JP1 is in the
3.3V position.

J12
Local watch dog timer reset (RST LWDT). Use this when J11 is set to the LWDT position when testing the watch
dog timer function. When a shunt is installed on J12 the local watch dog timer will reset causing the TPS3860x0
WDO signal to go low after timeout.

J10
External watch dog timer input terminal. Use this input when J11 is set to the EXT WDT position.
J9
TPS3860x0 WDO pin output.
