TPSM86637: High current with no load when input voltage is close to output voltage

Part Number: TPSM86637

Tool/software:

Hello, we are using the voltage converter in an application with a 4S LiPo battery (voltage max 16.8V, min 12V, nominal 14.8V) with the converter configured for 12V output. Currently we are also testing with a variable benchtop PSU. With no load attached to the converter and the benchtop PSU set in the range 13.5V-17V, we are reading 0mA current. When the benchtop PSU is set to values in the range 12V-13.5V, we read around 5mA consumed. Is this expected behaviour? And is there something we can do to mitigate this apparent idle power consumption? Does TI have other converters which do not suffer from this apparent discrepancy?
