LM5069QUICK-CALC: Design support of LM5069 for redundant system

Part Number: LM5069QUICK-CALC
Other Parts Discussed in Thread: LM5069

Hi Expert,

The customer is considering the LM5069 for below conditions.

Two input sources to support the output capacitance (3000uF) and loading is 3KW.

The input range is 36V~72V.

Condition 1:

Plug the 1st input source. The voltage is 36V,Now the output is charging to 36V and support the 3KW loading.

The LM5069 will make the hot swap control now.

Condition 2:

(Follow the Condition 1)

Then plug 2nd input source, the voltage for the 2nd input source is 72V.

The LM5069 will make the hot swap control now.

Expected the output capacitance will charging to 72V within 3KW startup load (Due to the 1st input source is 36V,so only the 2nd input will support the loading)

Can you support the LM5069 calculation for those conditions.

Thanks

Best regards,

Eric Lai
