7135 replacement... higher current regulation

Is there a slightly higher current chip with the same form factor as the 7135? Or, is .380 amps the best that can be done with that package?

there is some i know:

AMC7140 with 700ma http://product.ic114.com/PDF/A/AMC7140_D.pdf
CN5710 with 1 amp http://www.consonance-elec.com/pdf/datasheet/DSE-CN5710.pdf
CN5730 with 1.5 amp http://www.consonance-elec.com/pdf/datasheet/DSE-CN5730.pdf

they are slightly difference size. i think there are some people who ‘stack’ 7135 on top of each other to improve currents flow.

Stacking or piggybacking amc7135’s is the way its been done for years. A few times other chips where tried but it’s so easy to just buy loose amc7135’s and stack them that’s pretty much the standard everyone went with. The 105c driver was cheap and programmable with the attiny13. You could scavenge the amc7135 off another donor board or buy them loose at several places. If you want more regulated current just add more amc7135 chips until you reach your goal. There is a limit though. If I remember correctly, the amc7135 has a .2v overhead so as long as the battery loaded voltage is .2v above the led vf at the set current it will remain regulated at that current. Once the battery is below the vf plus the .2v overhaed its running direct drive at what ever the depleting battery can deliver in current at its loaded voltage to the led. Batterys that hold their voltage under high current loads will stay in regulation longer.

I am well aware of stacking, have bee guilty of it several times. My eyes and hands are not what they once were. I have an old Shadow light that has a driver that would be difficult to replace if I managed to kill it. I am also thinking about building a 16x7135 driver and would like to get just a little more out of it.

I asked because of the second driver, it needs a board mounted e-switch and with higher current chips I think I could leave a couple off and rig the side switch onto the board.

To my knowledge there is no higher current chip that can directly replace a 7135 on an existing driver.

0.38A is not the limit for that package size though, the CN5710 has the same package size and is rated for 1A. It can not directly replace a 7135 though, it has more legs and, more importantly, it’s a high side regulator (7135s are low side).

How about a LM317T? Just saying.

The OP is asking about a direct replacement for 7135s. Ok, I’ll admit I haven’t bothered checking the LM317T datasheet but I’m quite sure you can’t just remove a 7135, solder on one of these in it’s place and the driver will work as normal except with higher output.

I was asking about direct replacements, I figured there were none, at least I could not find any. There are some options, but they require extra components and would be best used in a new design. Thanks for the input.
