I know it is off-topic but the DCX65 can operate with DCC voltages up to 21V and it will provide reduced voltage to the motor?  That is a very important development for N (and smaller scale) DCC!

That is exactly the purpose of the DCX65 (see http://www.tran.at/Produkte/DCX65.shtml). And I agree that this is a major development. Just a warning, the DCX65 delivers a max of 0.25A continuously and is, as I mentioned, not yet available. But think of all that pager motors. Btw it is good to mention that officially the decoder is rated for 5V motors, but the realitiy is that motors rated between 3 and 8V are not harmed.

Other than the voltage drop through the full wave rectifier on board, and the voltage drop in the output transistors, decoders do not produce voltage lower than the voltage on the rails.

Since the minimum voltage the decoder is specced at is 7 volts, that's the minimum voltage you will send to the motor.

All of these decoders use PWM, on off switching of full track voltage (subject to the caveats in the first paragraph)

All that said, PWM can lower the AVERAGE voltage, and as long as you don't overheat the motor or otherwise break down the insulation on the motor windings, you are ok.

I just saw on the ESU site that the new LokPilot 5 Micro and MicroFx decoders are the size of the prior Nano Standard decoders (8mm x 7mm). They will also have slightly larger ones incorporating the Next18 sockets.  Unlike the Nano, they will be fully LS 5 compatible.
