XC9250/XC9251 Series ETR05023-004 30V Driver Transistor Built-In Step-Down DC/DC Converters ■GENERAL DESCRIPTION The XC9250/XC9251 series are 30V operation step-down DC/DC converter ICs with an internal driver transistor. The internal Nch driver transistor is driven by bootstrap to achieve a stable, high-efficiency power supply up to an output current of 2.0A. Low ESR capacitors such as ceramic capacitors can be used for the load capacitor (CL). A 0.8V reference voltage source is incorporated in the IC, and the output voltage can be set to a value from 1.2V to 12.0V using external resistors (RFB1, RFB2). 300kHz or 500kHz can be selected for the switching frequency.
