hi checkmate,
if possible, my input and also the Vdd i would like to share 12Vdc (easier as there's no other avail power source).
hi Exo,
i guess my input would be a steady 12v input as it's origin from the car's parking light and the signal light. However, the watt for the parking light i guess it's 10-15watt while the signal (fender) is about 5-10watt. I'm gonna connect direct from the source of the parking light and signal light (+ve) to the I1 and I2 terminal of 4030.
For the output... there's only a bulb (12v at 5-10watt).
Based on my wiring diagram, is the components used okie / match.
Coz i'm gonna have them stuck on a board... with connectors.
Also, regarding the transistor, it produce 600mA (frm the datasheet) but it is sufficient to power my bulb (also what watt will it be and it's voltage) as I'm looking for at least 12V with at least 5watt. Say my input to it would be at 12V between 5-15watt, is the output from the transistor same?
Should i use 2N2907 or 2N2907A. Any recommendation on transistor that would produce 12V at 5watt min. and input 12V at max 15watt.
Also... regarding the resistor, which watt applies here... 1/2 watt, 1 watt , 5 watt?
Sorry about so many question...
i'm an absolute dummies in component as i'm not EE stud.
I like to hands on experiment and to DIY most things...
it just gives me the pleasure.
P/s: The power supply to the chip... i have no choice but to share with either any activated bulb (parking light / signal) as there's the only 12V i get. Else, for a direct 12V (+ve) from the car battery might definitely screw up the chip (burned).
Thanks a million guys.
I really need this help.
Cheers.
