GENERAL DESCRIPTION

The XC9119D01A series is 1MHz, PWM controlled step-up DC/DC converter, designed to allow the use of ceramic capacitors. With a built-in 2.0Ω switching transistor, the XC9119D01A series can easily provide a step-up operation by using only a coil, a diode, a capacitor, and a resistor, connected externally.
