Dynamic Acoustic Vibration Effect, or just DAVE for short (patents filed 1-4-24)
Riding the subharmonics.

Designed the update PCB. Should fit nicely to the output capacitors and terminals and will need only two additional small wires. I will upload Gerber's after i test it, if someone else wants to update their DP100. At the end i decided for the more passive solution as its lot cheaper then the LTC7004.

Phil1977:
Maybe a stupid question, I´ll anyhow speak it out: May anyone imagine putting a small 5A capable relais into the output? Combination of the integrated Low-Side-FET-Switch with a High-Side-Relais feels like a no-brainer-solution for me, but is there by any way enough room for it? I´ll receive my own unit in a around 2 weeks...

There may be enough room for a super miniature relay on the top of the PCB where the caps and the main inductor is if its 10mm high it maybe would fit. But anyhow it would be hard to assemble as you would need more wires that go to the other side and would also need to cut the negative trace from the on board MOSFET to the output, probably better to use an extra SOT-23 Mosfet for relay control. It would not be a simple clean solution but doable without the extra mini PCB.

I think these are the smallest you can get for 5A: 10 * 6 * 5.65 mm (l*w*h)
