LMZ23605 efficiency

Other Parts Discussed in Thread: LMZ23605, LMZ35003, LMZ14203H, LM43603

Hi, I plan to use LMZ23605 to regulate a 14.4V-12V source down to 11.0V (@1A to 3A loading),  Is there any minimum Vin-Vout requirement?  I also cannot find the efficiency graph of any small Vin-Vout, what will be the expected efficiency when Vin = 12V and Vout = 11V@1A?

    Hi, Wang,

    Unfortunately LMZ23605  is intended to work in the output voltage range 0.8V to 6V. That's why you couldn't found any graph for Vout=11V.
    If you look for power module I would take into account LMZ35003 or LMZ14203H.

    As well TI has a lot of discrete  buck DC/DC regulators,  for example LM43603 will suit  our requirement
