May we have PMIC can dynamic adjust 4 outputs by I2C or SPI for SSD application?

Dear Sir

May we have PMIC can dynamic adjust 4 outputs(power sequence/enable/Vout voltage ) by I2C or SPI for SSD application?

Vin is 5V Vout is adjustable and output current is 4A/3A/3A/3A. like ACT8870.

    Hello,

    You could check http://www.ti.com/product/LP8758-E0 is that suitable for the application. Can you tell more details about the use case, average currents etc.?

    Thanks.

    Hi Sir

    The customer want use I2C(or SPI) to control output voltage after power on. for example, here after power on that buck1 =1V/buck2 = 1.8V/buck3=3.3V buck4=2.5V.

    and some condition they want to dynamic control let buck1 = 1.5V/turn off buck 2/ buck 3=2.8V/ buck4 =2V. and customer also help can control power sequence by dynamic.

    Hello,

    Ok, sounds like LP8758-E0 would be a good fit for this. It allows enabling/disabling outputs/changing the voltage level with gpio pins as well as with I2C registers.

    Thanks.
