XC9119D10AMR 1MHz PWM control, step-up DC/DC converter, compatible with ceramic capacitors
XC9119D10A series is a 1MHz, PWM-controlled step-up DC/DC converter that can use ceramic capacitors. With a built-in 2.0Ω switch tube, the XC9119D10A Series can easily obtain a boost circuit by connecting an external inductor, a secondary tube, a capacitor, and a resistor.
With a 1.0V (±2.0%) reference voltage and voltage divider, the output voltage can be up to 19.5V (max. Lx operating voltage: 20V), and the series can be used for general-purpose high-voltage power supplies, LCD panels, and OLED display power supplies.
With a switching frequency of up to 1.0MHz, chip inductors and ultra-small ceramic capacitors can be used to reduce the area and thickness of the board.
The series has a current limiting function (400mA (TYP.): VDD=3.6V) that limits the peak current flowing through the built-in switch tube. Soft-start time can be adjusted with external resistors and capacitors. The standby function enables the output to shut down (CE 'L'), at which point the chip will consume less than 1.0A.
