A dangerous algorithm written in C, prone to memory leaks (see Windows) Its described on page 95IIRC of Art of Electronics. Its similar to a darlington, but different. In the Sziklai, the small transistor and the big one are different sexes. Typically, the small one is NPN, and the big one is PNP. All the base current in the big one goes to the load as well, so its a bit more efficient. -- http://www.piclist.com#nomail Going offline?
