3 Operation

  1. Set jumper J13 to the enable position.
    • J13 can also be left open, as a resistor divider is used with VIN to pull the enable pin up. Enable threshold is ~600mV. Resistor divider R2/R7 can be changed to achieve different turn on voltages for VIN. By default, device will be enabled when VIN > ~1.8 V for default EVM. It can also be digitally controlled from a host through J13.
  2. Enable PS1, and PS2. Sequence is not important.
  3. VOUT should now read ~1.8 V.
    • VOUT at load will likely be lower than 1.8 V when load applied. The OUTS connection for feedback regulation is located on the COUT plane closer to U1.
  4. PG output (TP6) should also now be pulled up to VOUT and read 1.8 V.
  5. Vary the load as necessary for test purposes.
