TPS51980A TI POWER CONTROLLER IC chips QFN32

TPS51980A U7501 U7201 chip is a MacBook buck converter for the PP3V3_S5, PP5V_S4, and LDO PP5V_S5 power rail.

This chipset is located around the edge of the logic board, therefore, it is quite normal for it to short in the event of a water damage.

If you are missing SMC_PM_G2_EN or PM_SLP_S4_L you must first investigate & repair these before replacing the TPS51980A U7501 U7201 chip.
