XC9220 Datasheet (Torex Semiconductor) - Step-Down DC/DC Controller

XC9220, 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
