Abstract
A strobe light firing circuit is provided with an integrated circuit (10) for deriving both timing and power generating pulses. A field-effect power transistor (16) gates the power generation transients while effectively isolating the timing integrated circuit (10) from high transients during the switching of the transistor (16). Timing pulses from the timing circuit (10) are divided in frequency by a binary counter (38) and then sequentially applied at the output pins of a decade counter (40) for strobe timing sequence selection. A strobe light firing pulse is differentiated (48) to form a pulse for shutting off power generation pulses from time (10) for a time effective for the flash tube (58) to recover for a subsequent discharge.
