XC9242/XC9243 series 2A synchronous step-down DC/DC converters are a group of synchronous-rectification step-down DC/DC converters with a built-in 0.11Ω (TYP.) P-channel MOS driver transistor and 0.12Ω(TYP.) N-channel MOS switching transistor, designed to allow the use of ceramic capacitors. The small size allows for high integration and is suitable for a variety of applications.
The XC9242/XC9243 series from Torex Semiconductor are synchronous step‑down DC/DC converters featuring built‑in P‑channel and N‑channel MOS driver transistors. They support a wide input range, configurable output voltage and offer high efficiency for portable electronics such as mobile phones and cameras.
