343S00262 Power Management IC (Big) for iPad Pro 11 2nd Gen (2020)

Apple's 2020 update to the 11-inch iPad Pro brought the LiDAR scanner and a new camera layout, but its power still flows through one large main PMIC. When that chip fails, the iPad is usually dead, or it starts with odd display or touch behavior.

This is the Apple 343S00262 power management IC, the big PMIC, for the iPad Pro 11-inch 2nd gen (A2228, A2068, A2230). The listing gives its pin count as 342.

Signs it may be failing

• No boot with a good battery and no main line short.

• Abnormal current at power-on.

• Display or touch faults with good screen parts.

• A short traced to the PMIC.

Work carefully

Rule out the battery line and the smaller power chip, 343S00263, first. Then preheat the thin board evenly and remove underfill carefully, because pads under a large BGA are easy to lift.

After fitting, check the rails, then test boot, Face ID, LiDAR, touch and charging before reassembly. An AR app that maps the room quickly is a handy final check that the LiDAR side is powered properly.
