Equipment Setup

1. Set the power supply #1 (PS#1) for 21-V ±500-mVdc, 2.5-A ±0.1-A current limit, and then turn off
supply.
2. Connect the output of PS#1 in series with a current meter (multimeter) to J1 (VIN, PGND).
3. Connect a voltage meter across J1 (VIN, PGND).
4. Connect Load#1 in series with a current meter to J2 (VOUT, PGND). Turn off Load#1.
5. Connect Load#2 in series with a current meter to J2 (VSYS, PGND). Turn off Load#2.
6. Connect a voltage meter across J2 (VOUT, PGND).
7. Connect a voltage meter across J2 (VSYS, PGND).
8. Check all jumper shunts. JP1: connect 1-2 (External TS); JP2: ON; JP3: connect 2-3 (Enable
TERM_EN); JP4: OFF.
