XC9221 Step-Down DC/DC Controller

The XC9220/XC9221 series is a group of multi-purpose step-down DC/DC controller ICs. The ICs enable a high efficiency, stable power supply with an output current up to 3A to be configured using only a transistor, a coil, a diode, and two capacitors connected externally. Low ESR capacitors such as a .
