I have an LED current source circuit using 2N2907 transistors driven from a 595 shift register that will source 35mA. This will give me 350mA of drive, but I need more like 940mA. Will a P-channel MOSFET do this? I want individual transistors, SMT is fine. I could live with less then 940mA, but 350mA is too little. Please recommend a transistor replacement that will give me more drive. Alternatively recommend a very inexpensive replacement that will give me 7 lines of ~940mA ( only one one used at a time ) switchable from logic levels ( +-35mA max ).
Thanks!
Thanks!
