MPM82504-0001 Resistor divider

DC-DC Power Converters

Dears

I have an inquiry regarding MPM82504-0001.
Q1. Is it possible to use a hardware control method without PMBus control?
Q2. Is it possible to generate an output voltage using a resistor divider even if “Flash writing” has occurred?

Default configuration for dual 50A output
VIN :12V
VOUT : 0.85V
Ch1,2 : 50A
Ch3,4 : 50A

Thank you

Hi Henry,

Thanks for reaching out.

For your Q1: Could you please provide a more detailed description of what kind of control you want to make with hardware?

For Q2: From the datasheet (shown below), you can change the resistors but not the ratio of the resistor after you have written to the memory.

Dear Wento

Tnak your support.

I have a follow-up inquiry regarding Q1.

I would like to set the power output using an external resistor without using PmBus.

Is this possible?

I understood the answer to Q2.

Thank you

Hi,

Thanks for providing the information. By saying power output, could you please clarify if you meant output power? The module itself only determines the output voltage, and output current is set by the load itself as long as it doesn’t reach the current limit. You can only set the current limit by the PMBus.
