2 Setup
This section describes how to properly use the TPSM8286xAA0xEVM.
2.1 Setup
To operate the EVM, set jumper JP1 between ON and EN to turn on the device as shown in Input, Output
Connector and Jumper Descriptions . Connect the input supply to J1 and connect the load to J2.
2.2 Input, Output Connector and Jumper Descriptions
J1 – VIN/GND
Input and return connections from the input supply for the EVM.
This connector supports currents over 3 A and accepts up to 16 AWG wire.
J2 – VOUT/GND
Input and return connections from the EVM to the load.
This connector supports currents over 3 A and accepts up to 16 AWG wire.
J3 – PG/GND The PG output appears on pin 2 of this header with ground on pin 1.
J4, Pin 1 and 2 – VIN
Positive input connection from the input supply for the EVM
Do not use for currents above 3 A.
J4, Pin 3 and 4 – S+/S– Input voltage sense connections. Measure the input voltage at this point.
J4, Pin 5 and 6 – GND
Input return connection from the input supply for the EVM.
Do not use for currents above 3 A.
J5, Pin 1 and 2 – VOUT
Output voltage connection
Do not use for currents above 3 A.
J5, Pin 3 and 4 – S+/S– Output voltage sense connections. Measure the output voltage at this point.
J5, Pin 5 and 6 – GND
Output return connection
Do not use for currents above 3 A.
JP1 – EN
EN pin input jumper. Place the supplied jumper across ON and EN to turn on the module. Place the
jumper across OFF and EN to turn off the module.
JP2 – PG Pullup Voltage
PG pin pullup voltage jumper. Place the supplied jumper on JP2 to connect the PG pin pullup resistor to
VOUT. Alternatively, the jumper can be removed and a different voltage can be supplied on pin 1 to pull
up the PG pin to a different level. This externally applied voltage must remain below 6 V.
JP3 – VSET/MODE
VSET/MODE pin input jumper. Place the supplied jumper across PWM and VSET/MODE to operate the
IC in Forced PWM mode. Place the jumper across PFM/PWM and VSET/MODE to operate the IC in
Auto PFM/PWM mode. Remove the jumper to operate the IC with a fixed output voltage, which is set by
R4.
For the fixed output voltage configuration, R4 must be installed, R2 removed, and R1 shorted.
3 Safety Instructions
WARNING
Hot surface. Contact may cause burns. Do not touch.
WARNING
High currents may be present on the input and output. Use connectors J1 and J2 if the current exceeds 3 A.
