POWER CONTROL IC CHIP PMIC FOR NINTENDO SWITCH / SWITCH OLED MAX77620AEWJ / T

PMIC IC FOR POWER MANAGEMENT OF THE NINTENDO SWITCH / SWITCH OLED MAX7762AEWJ / T

The MAX77620AEWJ+T main power management IC (PMIC) (often referred to as MAX7762AEWJ-T). This IC is a key component of the power supply section in Nintendo Switch consoles (V1, V2, and OLED), responsible for the steady distribution of current to the processor (CPU), graphics processor (GPU), and RAM.

Package contents:

1× MAX77620AEWJ+T / MAX7762AEWJ-T PMIC chip

Note: Installing the chip in a BGA package requires advanced micro-soldering skills and professional equipment (hot-air station, microscope, appropriate flux).

Replacing the chip may help resolve the following issues, provided that they are directly caused by a faulty PMIC controller. Before proceeding with the repair, it is recommended to perform a full diagnostic check of the motherboard for short circuits and to verify the operational status of the other chips.

• The console does not respond to the Power button (the device does not turn on),
• No power draw or incorrect charging parameters (e.g., 0.00A on a USB meter),
• The startup process is stuck on the Nintendo logo (a so-called bootloop or restart loop),
• Short circuits on capacitors in the power supply circuit around the PMIC chip.
