Circuit & PBC Design for LED & Laser Diode


- Using Battery CR2 3V.

- 2 SPST Switches On/Off. 1 For Led 1 For Laser Diode

- 1 LED = (Cree XP-G)[url removed, login to view]~/media/Files/Cree/LED%20Components%20and%20Modules/XLamp/Data%20and%20Binning/[url removed, login to view]

- 1 Laser Diode. 10-15ma Draw (2.8-3.v)

-PCB max size = 17mm x 18mm

-Led, Laser Diode, battery and Switches to connect to PCB. Hopefully with micro connectors.

I am looking for 2 Modes for LED. 1 Mode for Laser Diode

On = 600ma, Push On 3 Sec(or another way) 300ma, also 300ma when battery V < [url removed, login to view] or whatever voltage you think is the one. I am also looking for a good efficiency driver and low parts cost. The stated ma, is ideal, but if similar a doable ma's are better for any other reasons I am not fixed on those.

A lot of similar drivers use 1 x AMC7135 chipset , for 350ma and 2 x for 700ma, as it offers some battery cut off protection and seems to be very efficient with li-ion batteries.

I have done some research, and for this battery 1 x AMC7135 seems good, but 2 would drive 700ma which is not realistic for a 3v battery.

For controlling modes the ATTiny13A seems to be the one mostly used.

I have seen other multi-output Pmic's, but dont want to influence your selection now.

I am looking for the PCB design in a ODB or AutoCAD dxf as well as a list of parts and an explanation of it. Before design, I will tell you where I need the connectors for switches, battery, led & diode.

I'm an electronics engineer. I've used laser diodes in my own projects (3d scanner) so I should be able to do this without much trouble. New to Freelancer, but not to circuit design!
