8.4.2 Supply Current Capability

The input supply must be able to supply the required input current to the LMZM23601 converter. The required input current depends on the application's minimum input voltage, the required maximum output current, the output voltage, and the converter efficiency η for this condition.

Equation 4. GUID-E4841F63-7241-442E-B828-488C0FE453D3-low.gif

As an example, assuming that the adjustable output voltage version of the LMZM23601 is used for a 5-V, 1-A output converter design with 12-V minimum input voltage. The conversion efficiency for this condition is about 85%. The required input current from the supply is 0.49 A, so TI recommends an input power supply with ≥ 0.5 A current capability.
