Part Number: DCPA10505

Hi team,

We introduce DCPA10505 however output power doesn't customer requirement,

Can customer parallel DCP10505 to support higher current output?

Thanks & Regards

DCPA10505 can be paralleled for increased for doubled 2 Watt output . See DCPA10505 product specification page 18 for additional details . Schematic for parallel is below.

Hi Tom

Do we have to use external clock or not

If the external clock is necessary ,how about the frequency ?

2) DCPA10505P single output used in parallel output operation, The synchronization feature allows easy synchronization to prevent power rail beat frequencies with no additional filtering .

Synchronizating frequency \range is 750kHz to 1000kHz.

Hi Tom

May I use DCPA10505 without external clock ?

I saw DCP02 series could be used without external clock for parallel application

Eddie:

Yes the DCPA10505P can be used in parallel operation without the external clock circuit. The output noise ripple will be more as- symmetric when not using an external clock circuit.
