Original question:

LM5143-Q1: 13.5VDC to 12VDC/200A controller solution

LM5143-Q1: 2-phase output current limit

PRABHAT RANJAN TRIPATHI
Intellectual 701 points
Part Number: LM5143-Q1

How much source and sink current is supported by LM5143-Q1?

When using in 2-phase configuration what is the limiting factor for output current drawn by the system at an output voltage of 18Volts, when input is 24 Volts?

    Hi Prabhat,

    The current limit setpoint is controller by the shunt value (the peak current per phase = 75mV/Rshunt). 10-15A per phase is a good estimate of capability, depending on power stage component selection, max ambient temperature and other factors. Use the quickstart calculator to simplify component selection.
