Setup Connection Description
J 1 7-LDO 1 Input/output connection for LDO 1 . VINLDO 1 can be connected to an external
supply or connected to another output voltage on the EVM. The EVM default
configuration connects VMAIN to VINLDO
1 . Remove R25 if a voltage other than
VMAIN is used as input to VINLDO 1 .
J 1 8-GND Return connection for LDO 1 and LDO2 low dropout linear regulators
J 1 9-LDO2 Input/output connection for LDO2. VINLDO2 can be connected to an external
supply or connected to another output voltage on the EVM. The EVM default
configuration connects VMAIN to VINLDO2. Remove R26 if a voltage other than
VMAIN will be used as input to VINLDO2.
JP 1 -DEFCORE Jumper allows you to select default core voltage at startup. Connect DEFCORE to
VBAT to select default as
1 .6 V. Connect DEFCORE to GND to select default as
1 .5 V.
JP2-DEFMAIN Jumper allows you to select the default main voltage at startup. Connect DEFMAIN
to VBAT to select default as 3.3V. Connect DEFMAIN to GND to select default as
3.0 V.
JP3- PS_SEQ Jumper selects power supply turn-on/ turn-off sequence. Connect PS_SEQ to VCC
to power the main converter up first and down last. Connect PS_SEQ to GND
power the core converter up first and down last.
JP4- GPIO PULLUP Jumper to select between VBAT and VMAIN for GPIO pull-up voltage on EVM
JP5-LOW_POWER Connect LOW_POWER to VBAT to assert LOW_POWER signal. Remove jumper
to deassert LOW_POWER signal. The ENABLE LP BIT must be set in VDCDC
1
register before low-power mode is activated.
JP6-BATT_COVER Connect BATT_COVER to VBAT to assert BATT_COVER signal.
S 1 -PB_ONOFF Normally open momentary pushbutton switch that, when pressed, connects VBAT
to PB_ONOFF input of TPS650
1 0
S2-/HOT_RST Normally open momentary pushbutton switch that, when pressed, connects
/HOT_RST input of TPS650
1 0 to GND
2.2 Setup
Perform the following procedure before operating the EVM:
1 ) Install the TPS650 1 0EVM software.
2) Connect input voltages and loads to the EVM.
3) Configure all EVM jumpers.
4) Connect the Molex cable between the EVM and the EV2300. Note
that the Molex cable must connect to the I
2
C connector on the
EV2300.
5) Connect the USB cable between the computer and the EVM.
6) Turn on all supplies and loads.
7) Run the TPS650 1 0EVM software.
