Replacement For The LM3909 LED Flasher / Oscillator


Posted on Feb 4, 2013

This page features a replacement circuit for the LM3909 LED Flasher / Oscillator using discrete components. The circuit is functionally the same as the integrated LM3909 but has a minor variation of the components used. Naturally the circuit will not be as physically as compact as the integrated circuit but it does offer the ability to adjust individual component values and may actually be less expensive that the integrated circuit.
