ADP1876 parallel operation

Hi,

It is possible. For a typical application, you can construct the Power section as is. Tie COMPx together to a common network. Tie ENx, and SSx together too. Populate separately Ramp1 and Ramp2 with same resistor from VDD. 

You can also check ADP1850 for your reference, and its Application example for Dual-Phase Circuit 50A. It has LTSpice model for your simulation.

Thanks!

Thanks for the response , what if we need 100 A , Can we use two ADP1876 in parallel ?

Hi Aravind,

The simplest way would be adding bleeder resistor to the output.

You can also do a 4-phase operation by adding a multiphase oscillator like LTC6902 and connect the outputs to SYNC of each ADP1850. You can also simulate 4-phase operation in LTSpice with LTC6902 and ADP1850. Thanks!
