at very high input voltage W ith extremely high-frequency ICs. A single-transistor Approach protects the SEPIC circuit from short-circuit fault conditions by pulling down the Vcpin (the output of the error amplifier) when the inductor current starts to run away Dur ing an overload or short circuit in the load (Figure 1). Pulling the VC pin low forces the IC to stop switching, skipping minimum on-time switch cycles, and allowing the Curre NT in each i
