XC9248Series

ETR05022-004

18V Driver Transistor Built-In Synchronous Step-Down DC/DC Converter

■GENERAL DESCRIPTION

The XC9248 series is 18V bootstrap synchronous step-down DC/DC converter with built-in Nch-Nch driver transistors.

With an input voltage range from 4.5V to 18V and a maximum output current of 2.2A, the series is suitable for digital home

appliance power supplies and can be used with small ceramic capacitors.

The series has a 0.8V reference voltage, and using externally connected resistors, the output voltage can be set freely from

1.0V to 12V.

The control method is synchronous PWM (Source/ Sink). The soft start time is internally set to 2.8ms (TYP.), also can be

adjusted using external capacitor.

With UVLO (Under Voltage Lock Out) function, the internal driver transistors are forced OFF when input voltage falls down

below 3.8V (TYP.).

The series includes over current protection, V_OUTshort-circuit protection, Lx short-circuit protection, V_OUTovervoltage

protection and thermal shutdown.
