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, VOUT short-circuit protection, Lx short-circuit protection, VOUT overvoltage  
protection and thermal shutdown.
