The 2-phase buck controller (IR36021) recommended for the T2080 core voltage supply (and implemented in the RDB) is obsolete.
Does NXP have a recommendation for a replacement controller that supports a manual VID programming facility (I2C or PMBUS)?
Use LTM4676A from Linear Technology. We have used it in our design with T2081 Processor.
Hi,
Is there any suggestion for TI power controller module with external switch?
There are no recommendations for replacing IR36021.
Use as Layerscape communications processor board schematic.
For example see the LS1088ARDB schematic:

This board uses the LTC3882 as buck converter.
Have a great day,
Pavel Chubakov
