Im wanting to make a work bench light using a SST 90 (flux bin N3) that I have. I'm thinking of machining a reflector and mounting the chip to a large CPU heat sink. I'm looking more for a flood light then spot. I was going to use the 5 volt side of an old computer power supply to power the driver.
Im looking at running 9 of the CAT4101s in parallel to provide up to the 9 amps of power. I was thinking I should be able to use a variable resistor on the RSET pin to fade the LED instead of adding the cost of PWM to the driver. Does anyone have any experience doing this?
What I have done before for the CAT4101's is machine out a base to clamp them down in and then just solder what I need to the pins. The aluminum base also acts as a nice heat sink for the drivers. Has anyone else used this many CAT4101's in parallel?
Looks like I can get everything I need for about $30 to make the driver, is there a cheaper driver out there that will power that LED the way I want?
I have some Cree XP-g's that I'm using 2 of the CAT4101's in parallel with an arduino running PWM that have been working great that is the reason I'm looking at them to make the driver.
Thanks in advance for your help!
