MMPF0100 unused SMPS pins

Hi there!

I use the MMPF0100 to supply an i.MX6 application.

Not all of the SMPS are necessary in my application.

The idea is to disable the unused SMPS (OTP - MMPF0100) and to connect all unused pins to GND.

Is this necessary/possible/usual?

Thanks for help.

Kind regards

Peter

Hi Peter,

Unused switching regulators should be connected as follows: Pins SWxLX and SWxFB should be unconnected and pin SWxIN should be connected to VIN with a 0.1uF bypass capacitor.

Best regards.

Jorge.
