Hi gang,
I'm considering developing a new driver for the high-power LED automotive market.
My big question is: would anyone want this instead of DerWichtel's driver?
Characteristics of this driver would be:
Similar in operation and based on the IS1006 driver.
Suitable for use in 12 volt automotive application without external components (except hi/lo switch and LED).
Linear Current regulation - ideal for LEDs, won't cause electrical interference.
Current up to 10A, possibly more.
1 or 2 modes, either or both adjustable.
Modes selectable by toggle switch, not clicky, etc.
Thermal protection for the driver, which can also protect LEDs if designed properly.
Linear regulation, which means only moderate efficiency, and requires 3-4 LEDs in series, and good heatsinking for the driver.
Price $35-40, including thermal mounting pad.
Size around 1.5" x 1.5" x 0.5".
Mounting by single 6-32 or M3 screw. A second mounting hole would be provided for optional use.
I'm looking to see what the interest is in such a driver, and any suggestions for features I haven't thought of.
Suggested uses:
Three SST-50s or SST-90s in series, full output when engine is running, reduced output when engine is off and battery is not fully charged.
3, 6, or 9 XM-L in 3S1P, 3S2P, or 3S3P configuration, full output whether engine is running or not.
4, 8, or 12 XM-L in 4S1P, 4S2P, or 4S3P configuration, full output when engine is running, quite reduced output when engine is off. Can be tricky to reach full 3A/LED.
Could also be used for single or dual (2S1P) XM-L or dual SST-50 applications. The efficiency would suck, but maybe that doesn't matter.
Any comments are welcome.
