XC9250 Datasheet (Torex Semiconductor) - 30V Driver Transistor Built-In Step-Down DC/DC Converters

XC9250, 30V Driver Transistor Built-In Step-Down DC/DC Converters

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
