Input/Output Connections
2-2
2.1 Input/Output Connections
The connection points are described in the following paragraphs.
2.1.1 J1−Vin
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.
2.1.2 J2−GND
This is the return connection to the input power supply.
2.1.3 JP1−Enable
This is the enable pin of the device. The enable pin is pulled up to Vin by an
onboard pullup resistor. Placing a jumper across pins 2−3 of J1 shorts the
enable pin to GND; thereby disabling the device. Placing a jumper across pins
1−2 of J1 connects the enable pin to Vin and enables the device.
2.1.4 J3−Vout
This is the positive output for the device.
2.1.5 J4−GND
This is the return connection for the load.
2.2 EVM Operation
An input power supply and a load must be connected to the appropriate EVM
connectors in order for the EVM to operate. The absolute maximum input
voltage is 7 V. The TPS6222x is designed to operate with a maximum input
voltage of 6 V. Short pins 1−2 on jumper J1 (labeled ON) to enable the device.
Connect a load not to exceed 400 mA to the output of the EVM.
