SLVUCB0A September 2021 – November 2022 TPSM82864A , TPSM82866A
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. |
