Description
C.C. Source for LEDs
Constant current source for a white LED lamp
This circuit ensures a constant supply current (pre-relayed in the range 25....440mA from the semi-adjustable RV1) of a maximum of 24 white LEDs that can equip a portable camping lamp for example. The voltage source can be from a battery or 4.5-6V batteries.
The regulating element is an N-channel MOS transistor. For example, a more common IRF740 or equivalent transistor can be used.
Have fun with it!
