1 A LAMP FLASHER


Posted on Feb 6, 2014

National LM195 power transistor is turned on and off once per second for flashing 12-V lamp. Current limiting in LM195 prevents high peak currents during turnon even though cold lamp can draw 8 times normal operating current. Current-limiting feature prolongs lamp life in flashing applications. -R. Dobkin, `Fast IC Power Transistor with Thermal Prot
