Cyclone 10 LP PMIC suggestion

Other Parts Discussed in Thread: TPS54320, TPS54424

Hi guys,

since Cyclone 10 is not on ti.com/fpga yet can you recommend an efficient step-down for supplying the following 2 rails: 1.2 V core voltage for an Altera (Intel) Cyclone 10 LP and 3.3V for a LVDS Deserializer? The requirements are the following:

Vin = 5 V
Vcore = 1.2 V @ 3 A
Vlvds = 3.3 V @ 3 A

Thank you,

Franz

Franz,

TPS54320 (3A) or TPS54424 (4A) perhaps?

John,

so you're suggesting 2 separate bucks instead of a single PMIC for both rails?

Thanks,

Franz

Franz,

You did not specify. There may be a PMIC, but not from our group. Do you need just the two outputs?

Franz,

I will close this thread for now. You can re-open it at any time.

Hi John,

thank you for your support!

Your recommendations of individual bucks helped us move forward, since this FPGA doesn't need sequencing anyways. So a PMIC is not needed. They will be using two TPS54318.

Best regards,

Franz
