Input/Output Connector Descriptions
2-2
2.1 Input/Output Connector Descriptions
2.1.1 J1 – VBAT
This is the positive connection to the input power supply. The leads to the input
supply should be twisted and kept as short as possible to minimize EMI
transmission.
2.1.2 J2 – GND
This is the return connection for the input power supply.
2.1.3 J3 – VOUT
This is the positive connection from the output of the SEPIC power supply.
Connect this pin to the positive input of the load.
2.1.4 J4 – GND
This is the negative connection from the output of the SEPIC power supply.
Connect this pin to the negative input of the load.
2.1.5 J5 – LDOOUT
This is the positive connection from the output of the LDO power supply.
Connect this pin to the positive input of the load.
2.1.6 J6 – GND
This is the negative connection from the output of the LDO power supply.
Connect this pin to the negative input of the load.
2.1.7 J7 – PGOOD, LBO
Pin 1 of this jumper is the PGOOD output of the TPS61130. Pin 2 of this jumper
is the LBO output of the TPS61130. Both signals are pulled up to Vout through
a 1-M
Ω
resistor on the PCB.
2.1.8 JP1 – SKIPEN
This jumper enables or disables SKIPEN by connecting the shorting jumper
to either the ON or OFF position. With SKIPEN set ON the part goes into a
more efficient pulse skip mode of operation at light loads.
2.1.9 JP2 – EN
This jumper enables and disables the SEPIC portion of the EVM.
2.1.10 JP3 – LDOEN
This jumper enables and disables the LDO portion of the EVM.
