Rocked yet... Another hot led swap tonight for a sl member!
Hey guys. Just an update I am putting on all of my posts. Some of you swappers may know that the an7710sp power IC is no longer in production and not available anyplace in the usa. This was a wonderfull package size that was an exact match to the oem. Engifineer "Dave" did a great job locating it and figuring out the overall hvac mod so kudos to Dave!
This has caused a small delay in my shipping until a reliable alt was found and tested out. The new power ic is a bit larger but actually a tad quicker to install. I tested the chip thermally without a sink and it has no issues with the small requirements of the leds and is quite overbuilt! Since the original power ic has been axed, there may be different options people come up with. This is my choice to run with this package size and install method and it will be included in all of my kits. It will come pre-cut but not pre-bent as it could cause shipping issues in bubble envelopes. The legs are cake to bend with just your finger.
Below is an example of one of the chips I have been testing. The actual unit that will be in the kits is a different brand, but same chip basically
Excuse the small amout of flux on the board *LOL* Just a test unit!
This is what the new power ic will look like installed. Again this model number chip works perfect but is not the unit I will be including in the kits. Visually they are identicle. Also to note the center leg is bent the opposite way and is attached to the ground pad "common" for the old power IC. The mount is rock solid and there will be no issues.
