PMIC for fpga

[Michaelscott237]

Hey, i have board which integrates two  fpga's which needs several different voltages.

My main power is 12v

The first is fpga requires  1.2v for core and 3.3v for vccio and the second is  requires 1.0 for core, 3.3 for some vccio, 1.0v for serdes core, 1.8 for aux and 1.1v for some vccio (for lpddr) 

So i will need buck converters and ldo's for the serdes and aux power. I also need to power lpddr4 which for that i use a ti pmic which requires 5v and input that can be received from my main power. 

For now i used lt8653 converters and tps74901 ldo's to power everything but i wanted to know if you have a PMIC to replace all this power system that can fit for my requirements.

Thanks in advance

Hi Michael

What are the loading capability for each regulators your required?

[Michaelscott237]

Hey,
First fpga required 1.2v and 3.3v and has about 40mW power consumption.
Second fpga requires 1.0v core, 1.8v aux, 1.0v and 1.8v for serdes core and aux and 3.3/1.1 for io.
Power consumption around 500mW.
Enet phy requires 400mW.
Lpddr pmic requires 5v and 4-18v input.
Consumption around 200mW.

Regulators will power only serdes block and core voltages

1:For the 5V input I recommend MC34PF8100.

Thanks, but its overkill for my design.
Thanks anyway
