PMIC for LPDDR5/5x

DC-DC Power Converters

Hello,

Looking for is there any DC-DC module (with I2C/PMBus) or PMIC recommendation dedicated for LPDDR5 / LPDDR5x application?

i.e. VDD1: 1.8V @ ~1A, VDDH & VDDL: 1.05V @ ~6A, VDDQ: 0.5V @ ~1.5A

Thanks & regards,

Hi Ping,

We have several PMICs for DDR5 applications, is a 4-channel PMIC all that you need for the design?

Hi Ryan,

I need the PMIC for LPDDR5 / LPDDR5x (not DDR5).

3-channel PMIC is good enough for simplify as I take the advantage of share VDDH & VDDL supply rails in single voltage.

Below is the LPDDR5x power pin name, voltage and current requirement.

VDD1: 1.8V @ ~1A

VDDH & VDDL: 1.05V @ ~6A

VDDQ: 0.5V @ ~1.5A

Thanks & reagrds,

Hi Ping,

Sorry for the delay. I cannot disclose information about our LPDDR5 PMICs on the public forum. However, please submit a ticket here to get connected with an MPS FAE/Sales Engineer directly.
