All this talk about high current LEDs ... time for me to add another twist. Many of us use the WS2801 for driving RGB LEDs that don't require more then 20mA per channel. It works great as each channel on the WS2801 can provide up to 50mA in constant current, or up to 100mA in constant voltage, thoug…

140mA. Voltage to the NPN and IC will be 5V. Voltage to the LEDs will be 12V.
