LMZ23608: no load operation

Part Number: LMZ23608


We have chosen LMZ23608 module for speeding up our design. Input voltage: 11 ... 21V. Output Voltage: 5V. Max output current: 6A. I think it will all work fine. We have only one concern. Our minimum  output current can be as low as 0 (ZERO) Amps. In this respect I am not sure regarding module  control loop stability,  module heating, module internal componets stress, etc.

Also it is difficult to rely on PSPICE models as they were mathematically prepared for the case when RLoad is not infinity.

Did anyone try to use this module at no-load condition? What is the value of minimal load (if any)?

Any help appreciated!

Thank you, Andrei
