Hello all,

a few minutes ago Gustav22 posted the pdf in German.

THANKS A LOT, GUSTAV22.

Hi Rob,


thank. Of course UCC37324 is a very good power MOSFET driver. I think that you can use it without any problem.

As you are going to make a PCB I book in advance a couple for me.

One consideration:

1 - make the design in order that when the oscillator is not connected to the driver the MOSFET is  in OFF state!!

2 - put all the 3 driver set on the PCB....as the power MOSFET MUST be put near the ring (inside or outside).

3 - If I'm allowed to make a proposal:  design the DDS oscillator in a way to obtain either 3 asynchronous output to driver PCB or, using the CD4060 (or software) deliver a synched set of 3 frequency. In this latter case should be possible to vary only one of the 3 freq and obtain as output a synched set with proper programmable division like: :3, :7, :49.  Please before doing anything let's discuss and set a specification in order to avoid re-programming!

Many thanks for your cooperation. I do assure you that this time you will see that the effort will paj for itself.  Of course I'll book for this new PCB as well, please tell me an approximate budget.

I do appreciate very much your work. In the past I did several time that same job but with different tecnologies.....

Wait for your reply

Hi Roberto,
1. as long as the input is below the threshold of the UCC37324, when the oscillator is off then the mosfet will also be off. Refer to Spec.
2. Yes all three drivers on one board but the MOSFETs will be off the board and inside the ring.

3. I have not got much further with the DDS design yet. Only the spec. of the parts invloved and the frequencies will not be synchronised at all.

Glad to help your research.

1. finch? l'input ? sotto la soglia del UCC37324, quando l'oscillatore ? fuori allora del mosfet inoltre sar? disinserito. Riferir a spec. 2. S? tutti e tre i driver su un bordo ma i MOSFETs saranno fuori del bordo e della parte interna l'anello. 3. Non ho ottenuto molto ulteriore con il disegno della DDS ancora. Soltanto spec. delle parti invloved e le frequenze non saranno sincronizzate affatto. Felice di aiutare la vostra ricerca.

Regards

Rob

Hi Rob,

many thanks. I agree on all. I'm writing for you a set of requirements to discuss on. Just wait a moment.

Roberto.

Grazie per il tuo italiano!
