found another one i remembered by woop..




TPS61201 laser driver
this is a layout for a constant current laser driver using the TPS61201 chip. it should work with down to 0.3v input , u1= TI TPS61201, I1= coilcraft LPS3015-222MLB, C1-3= 10uH ceramic, C4= low value ceramic, Rsense= selected using R=0.5/I (where I is the required current). this driver should not be used without a load. and LD- must never be connected to Bt-. power source can be a single AA cell.

As I've posted a few times before.... the original Manufacturer
Design Engineer gets the Credit for the circuit...

Here is the Data Sheet of the regulator mentioned above..

http://www.national.com/ds/LM/LM3410.pdf

The board layout can be credited to the person that laid
it out...
