XC9270, XC9271 Series 30V Driver Transistor Built-In Step-Down DC, DC Converters ETR05048-001a ■GENERAL DESCRIPTION The XC9270, XC9271 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 incorp
