[jhu corrections]DVPWM is a PWM driver/dimmer originally designed for very simple LED lighting. It is built to be small, robust and convenient.
DVPWM is It has one single control: a PWM driver [rotating knob with on/dimmer] originally designed for very simple LED lightingoff switch attached. It In "off" position, the circuitry is built to [be] small, robust and convenientcompletely offline.
It has one single control: a rotating knob with on/off switch attached. In "off" position, [the] circuitry is completely offline. * '''Input''': 6-15 VDC. [With input voltage polarity] inversion protectioonprotection, suitable for dirty or noisy power supplies [Yes!!!].* '''Output''': "high" frequency [? kHz] PWM with duty cycle ranging from almost zero to almost 100% [Yes!!!]* '''Maximum admissible current''': 5A with SMD fuse on-board. This makes it probably overkill for small lighting, but will allow you to power about 25m of standard LED stripe or even small electric motors [Yes because there is a beefy high voltage spikes free wheel diode protection].* In most cases, more than one DVPWM can be combined for RGB lighting ('''common ground''') [Yes!!!]

Thanks to Joël H for the schematic. He made it with Kicad and his little brain [I maybe may have a relationship with Homer Simpson, which who is actually my idol-Jo]

PCB design was achieved with [http://eda.eremex.com/products/topor/ Topor], a piece of software which truly amazes me. Through recursive contemplation of the routing algorithm, I was able to shorten the track lengths to an almost minimum and reduce the number of vias to zero. an absolute minimum [zero !!!] . The output from Topor was then imported into Kicad again, because we couldn't be bothered to learn new things so early after sunrise.
PCB size is 26x37mm. Height from frontplate (if applicable: circuit secured to frontplate using the knob's nut): 22mm
