XC9248A085QR-G

18V Driver Transistor Built-In Synchronous Step-Down DC/DC Converter , 2.2A SOP-8FD

Product Overview

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.
