XC9223/XC9224 Series 1A Driver Transistor Built-In Step-Down DC/DC Converters ETR0509_017 ■GENERAL DESCRIPTION ☆Green Operation Compatible The XC9223/XC9224 series are synchronous step-down DC/DC converters with a 0.21Ω (TYP.) P-channel driver transistor and a synchronous 0.23Ω (TYP.) N-channel switching transistor built-in. A highly efficient and stable current can be supplied up to 1.0A by reducing ON resistance of the built-in transistor. With a high switching frequency of 1.0MHz or 2.0MHz, a small inductor is selectable; therefore, the XC9223/XC9224 series are ideally suited to applications with height limitation such as HDD or space- saving applications. Current limit value can be chosen either 1.2A (MIN.) when the LIM pin is high level, or 0.6A (MIN.
