DC-DC Power Converters
1

Hi,
In my design I am using MPM54304GMN-0001 part, please suggest how to set output voltages by using MPS Virtual Bench Pro4 .0.
Interface I2C and external voltage divider resistors used, please check image of schematic for your reference and let me know any changes required.

1.Vout1:
Expected value is 3.3V, but reading value is 5V
2.Vout2:
Expected value is 1.8V, but reading value is 2.0V
3.Vout3:
Expected value is 1.2V, but reading value is 2.4V
4.Vout4:
Expected value is 1V, but reading value is 3.4V

Hi @prabhu,

For MPM54304GMN-0001, the default is to set through external dividers.

The output of the device can either set by I2C or external resistors. So, if you want to use via I2C, you’ll have to remove the resistors and tie the feedback to Vout directly as shown in the image below. You can refer to the “0000” suffix code configuration table to program through I2C values.
