[WIP] 17mm DD+single-7135 driver / single sided / Dual-PWM

[wight]

@cajampa

Thanks wight for clearing up my confusion, you are correct i had confused the two.
And now i know that a DD’s FET driver is stone cold, i had thought heat could be a problem nice that it is not. Is it possible to make a linear driver with this kind of FET and the attiny? or is that another animal altogether

You’re welcome. Yes, it is possible AND yes it is another animal altogether. The driver is a WIP: A20LDX / A17LDX. The circuit / schematic has been tested and functions (to some degree or another).

Also note that led4power has built a linear driver called the LD-1 using this sort of FET and a PIC MCU rather than an ATtiny13A. All modes are constant current without PWM. Led4power’s driver is available for sale: FS: LD-1 driver (5Amp pwm-less linear)-SOLD
