Suitable transistor or IC to run 1 Watt LED in low voltage? Answered
I want to run 4 x 1Watt LEDs from a 3.7V source (10000mAh).
LED DC Forward Current: 350mA
The purpose is to sue it with a motion sensor.
Please suggest a transistor or IC with maximum efficiency.
Update: I found that the "IRF 540" Mosfet is a good solution.
