    Interesting. I’m not seeing any mention of USI 339S00912 online, and USI Global’s website doesn’t mention any identified products with 802.11ax or BT 5.0 support. I guess they might just be custom-packaging a BCM chipset for Apple.

    One of the CD3217B12 on the left side is actually a CD3218B12ACE2, most likely the very top one. The CD3218B12ACE2 is responsible for the MagSafe 3 connector.

    Texas Instruments LP8548B1 is the Keyboard Backlight Driver here. It was used as both LCD and keyboard backlight driver in previous Macbooks, but not anymore. The new LCD backlight driver is RAA209100. It drives MOSFETs on the other side of the board (same location) connection directly to the LCD connector. The listing could be updated accordingly.

Why so many LDO regulators? Aren't they very inefficient?

allanxp4 -

In practise, the efficiency of an LDO regulator is dependent on how much voltage it is dropping. While operating, an LDO is effectively a resistor that varies in real-time to ensure its output voltage stays stable despite changes in load current.

Power = I (current) x V (voltage)

Since an LDO is a resistive element, yes, it burns off energy as heat in this process. So an LDO dropping 18V to 5V could be very inefficient, more so when driving a higher current load as shown by the formula above. However, if an LDO is used to generate a 3.3V rail from a 5V rail, it is dropping just 1.7V, resulting in less power dissipation for the same load current.

You’re right, using an LDO for a large voltage drop is not good electrical design. But LDOs have excellent noise rejection performance, meaning they can take a noisy rail from a switching buck/boost converter with lots of transient or high-draw components on it, and create a much cleaner rail for lower-current, more sensitive devices. This is what I expect Apple’s doing.

iEvan -

LDOs drop the difference in voltage as heat, yes - hence the voltage difference between input and output determines the efficiency (eg a 3.0v LDO fed by 6.0v is 50% efficient).

In many cases where LDOs are used in designs the amount of lost power is negligible as the current being drawn is so small - simply not worth using a switcher for that rail. Also, LDOs typically have cleaner output so often an LDO is used to isolate an analog subsystem from noise on the main (digital) system rails.

Hugo -

+ some designs will have both a switcher and an LDO for the same power rail and switch to the LDO when the current is very low. Switchers get inefficient at low currents, so having both can improve efficiency.

Dan K -

Will you have MacBook Pro 16" 2021(Apple M1 MAX inside) Chip ID?

JJ Wu -

Hello! We currently don’t have chip ID plans for the M1 Pro Max version.

Arthur Shi -

I’m planning a few projects, can someone provide the logic-board dimensions?

Jordan Hunter -

Ahh perfect the CD3217B12 will ultimately fail on these like the CD3217 & CD3215 before them

Thomas Goldscheck -

One of the CD3217B12 in step 5 on the left side is actually a CD3218B12ACE2, most likely the very top one. The CD3218B12ACE2 is responsible for the MagSafe 3 connector.
