TPS51216-EP: Device suitable for low current application ?

Part Number: TPS51216-EP
Other Parts Discussed in Thread: TPS54116-Q1, TPS7H3301-SP

Hi All,

we plan to use the TPS51216-EP for a high reliability (space) application with DDR3 DRAM (1.5V), where space saving is an important point of view. Since this device may drive up to 20A VDDQ current, all reference designs introduce large MOSFET devices. A maximum current of approx. 3A VDDQ would serve our needs. Our Vin voltage will be in range 9 to 12V.

So, anyone used this device for a low current application with small MOSFETs ? Is this device suitable for this application at all ? In fact, we did not found any other all-in-one solution with such a high reliability, otherwise we would haven chosen the TPS54116-Q1. May be there exists another appropriate solution ?

Thanks in advance and best regards,

Heino Knief
