2.3.3 Boost Mode Verification

  1. Turn off and disconnect PS1.
  2. Set Load #1 to 3.7V and 2A current limit.
    Note:

    If Load #1 connected from BATTERY-J5(2) to PGND-J5(1) is not a four quadrant supply, remove Load #1 and use PS1 (disconnected previously), set to 3.7V, 2A current limit and connect across BATTERY-J5(2) to PGND-J5(1).

  3. Remove shunt JP20 to enable boost mode.
  4. Connect Load #2 across VAC-J1(2) and GND-J1(1).
    • Measure → VBUS (VBUS-TP7 and PGND-TP25) = 5.0V±0.2V
  5. Turn off and disconnect power supply.
  6. Remove Load #2 from connection.
  7. Reconnect shunt JP20.
