The XC9208 series is a synchronous step-down DC/DC converter with a built-in P-channel driver transistor and synchronous rectification. This series is ideal for applications requiring high efficiency and a small footprint. The device integrates a P-channel MOSFET for the switching transistor and provides a stable power supply with an extremely small circuit. The small CL auto discharge function ensures that the output voltage is quickly discharged when the IC is turned off.
