2.1.2 Jumpers

  • J1 — Connect J1:1-2 to enable the device or J1:2-3 to disable the device. To evaluate a unique EN_UVLO, please use the equations provided in the data sheet for calculating R5, then populate on the EVM, and remove the J1 jumper.
  • J2— Connect J2:1-2 to put the device in Auto mode or J2:2-3 for FPWM (fixed frequency). If synchronization to an external clock source is required, remove J2 jumper and hook-up clock to test point "SYNC."
  • J3 — PG is an open-drain, output signifying VOUT regulation. Connect J3:1-2 for VCC (3V) pull-up voltage, or, J3:2-3 for VOUT pullup voltage. Note the maximum voltage PG can sustain is 20V.
