343S00263 Power Management IC for iPad Pro 11 2nd Gen (2020)

The 2020 iPad Pro 11-inch has a big main PMIC and a 169-pin power chip alongside it. If the smaller one fails, the iPad can lose a rail it needs to start, even though the main PMIC looks fine.

This listing sells the Apple 343S00263 power management IC for the iPad Pro 11-inch 2nd gen (A2228, A2068, A2230). The listing gives its pin count as 169.

When it may be the cause

• No boot while the main PMIC outputs are present.

• A missing rail that this chip supplies.

• A short on its supply traced to the chip.

• Damage after a bend or liquid.

Helpful tip

Measure this chip's rails separately from the main PMIC's rails. That way you know which of the two is at fault before taking on a BGA job. It also saves heating the large main PMIC when it doesn't need to be touched, which lowers the risk to the rest of this thin board.

Fit with a preheater and fresh flux, then test boot, Face ID, cameras and charging. With those working, the iPad is ready for reassembly.
