PHOTOFLASH_SUPPLY
Flybcck or ringing choke oscillator is free-running when voltage on regulator capacitor C2 is less than zener voltage for reference diode D2, but converter action is halted when desired output voltage is reached. Circuit then periodically replaces charge lost by capacitor leakage.Energy conversion efficiency can therefore exceed 50% theoretical upper limit of most conventional photoflash circuits.-R. J. Sherin, Efficient Photoflash Power Converter, Electronics, 33:4, p 57.
