The MAX14745 Buck regulators feature a variable frequency mode for increased efficiency during light-load operation. However, there is a feature where pulse frequency modulation can be switched to peak current mode for noise sensitive applications. However, efficiency will be compromised in that mode. Please see bit 7 (Buck1LowEMI and Buck2LowEMI) of Buck1Vset and Buck2Vset registers. If you are concerned about EMI then you should use the lowEMI feature. The buck converters can output load current of up to 200mA with 900nA quiescent current.
The selection of inductors is explicitly recommended in the datasheet page 62. Device is recommended to use with 2.2uH inductor as said on page 62 Table 36 of the datasheet.
