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 trans-
mission.
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 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 power supply. Connect
this pin to the negative input of the load.
2.1.5
J5—LBO
The LBO pin is an open-drain output configured with a 1M pull-up resistor.
2.1.6
J6—GND
This is the ground connection for the LBO pin.
2.1.7
JP1—SYNC
This jumper enables or disables the power save mode at light loads. If SYNC
is connected to VBAT, the power save mode is disabled. Connecting SYNC to
GND enables the power save mode. When the SYNC pin is not connected to
VBAT or GND, the switch of the frequency of the device will synchronize to a
user-provided signal of 500kHz to 700kHz.
2.1.8
JP2—EN
This jumper enables and disables the TPS61090 on the EVM.
2.2
Setup
Connect an input supply between J1 and J2. The voltage range on this supply
should stay between 1.8V and 5.0V. Connect a load between J3 and J4. En-
able the output by positioning a jumper to connect the EN and ON pins. Config-
ure the SYNC jumper to the desired setting.
