Hello,

I am looking for a Circuit for constant pulse energy control switching modew power regulator using LM 317E with vco
Pulse width of the Bulb voltage/current out out will change inversely with the prevailing battery
voltage. Thus energy per pulse is constant. Reruired for a constant beam light intensity for a hand torch with 4 Zinc cardon or Penlite cells.
Bulbs rated 3.2/3.8/4.8/6 with 5 to 10% tolerance.
