Jumper Information

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 Pull-up

TPSM82866AA0PEVM only.

PG pin pull-up 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 6V.

JP3 – VSET/VID

TPSM82866CA3PEVM only.

Remove the jumper before taking EN high to start-up at the output voltage set by R4. After start-up, install the jumper across VSET/VID and HIGH or LOW to control which VOUT register is active.

JP3 – VSET/MODE

TPSM82866AA0PEVM only.

Remove the jumper before taking EN high to start-up at the output voltage set by R4. Or place the jumper across PWM and VSET/MODE or PFM/PWM and VSET/MODE to operate the IC with an output voltage determined by R1 and R2. After start-up, place the supplied jumper across PWM and VSET/MODE to operate the IC in Forced PWM mode or place the jumper across PFM/PWM and VSET/MODE to operate the IC in PFM/PWM mode.

To properly set the start-up voltage with R4, the jumper on JP3 (VSET/VID or VSET/MODE) must be removed before EN is applied.
