    Abstract: A camera strobe recharging IC includes a one-shot unit, an R-S latch block unit, a PWM control unit, and a ready control unit. The one-shot unit provides square wave signals. The R-S latch block unit is electrically connected with the one-shot unit. The PWM control unit includes a reference voltage source, an oscillator, a PWM comparator, a voltage boost comparator, and a current source. The ready control unit includes an FET, which has a gate contact electrically connected with an output contact of the R-S latch block unit. Accordingly, the present invention is compact and structurally tiny to facilitate integration and is good at modulating charging current, accelerating charging, and automatically recharging.
