PF0100 : Schematic is SW1ABC Single Phase with F0 OTP configuration

[koichisakagami]

Dear community,
We have been developing our product with iMX6Q and PF0100.

We designed the PF0100 Schematic for SW1ABC Single Phase.
In this configuration, all phases A, B, and C, are connected together to a single inductor.

But we implemented the F0 type PF0100 chip to custom board in the mistake.
The F0 type Pre-programmed OTP configuration is  (SW1AB Single Phase, SW1C Independent Mode).

Reluctantly we are debugging as above situation.
The iMX6Q is working without any problems at the moment .

[Question]
In case of continuing to use ,Is there any problem occurs?

Best Regards,

Dear Artur san,

Thank you for your advice.

We replace the F0  MMPF0100.

It is out of specification and not allowed to connect the SW1A/B/C regulators together when they are configured as SW1A/B single phase and SW1C independent. It may lead to excessive direct current consumption, chip overheating and even permanent chip damage. So, you have to replace the F0 MMPF0100 part with NP part and then program it with your own custom OTP configuration where the SW1A/B/C regulators are configured for single phase mode.

Have a great day,
Artur
